Functional Description The SKY65165-11 is a three-stage, HBT InGaP device optimized for high linearity and power efficiency. It contains all of the needed RF matching. An in-module active bias circuit is included within the device for all three amplifier stages, which provides excellent gain tracking over temperature and voltage variations. The first and second output stages are independently supplied using the VCC1 and VCC2 signals (pins 15 and 14, respectively). The DC control voltage that sets the bias for all three stages is supplied by the VC_BIAS signal (pin 4). The Evaluation Board includes shunt decoupling capacitors on these pins to suppress any possible bias affect on the RF signal at low frequencies. The SKY65165-11 includes an internal PA enable control pin (pin 5) for fast RF on/off control. Zero volts turns off the PA while 3 to 5 V enables the PA. The device also provides an output power detector voltage, VDET, at pin 8. Pin 1 is the RF input and pins 10 and 11 are the RF outputs. External DC blocking or RF matching is required on the RF output.
Grounding is through several ground pins and the package center ground. These features make the device suitable for wideband digital applications where PA linearity and power consumption are of critical importance (e.g., WLANs). The device has been characterized with the highest specified data rates for 802.11b (11 Mbps) and 802.11g (54 Mbps). Under these stringent test conditions, the device exhibits excellent spectral purity and power efficiency.
Electrical and Mechanical Specifications The absolute maximum ratings of the SKY65165-11 are provided in Table 2. The recommended operating conditions are specified in Table 3 and electrical specifications are provided in Table 4. Performance characteristics for the SKY65165-11 are illustrated in Figures 3 through 6.

DATA SHEET • SKY65165-11 POWER AMPLIFIER
Evaluation Board Description The SKY65165-11 Evaluation Board is used to test the performance of the SKY65165-11 PA. A typical application schematic diagram is provided in Figure 26. An assembly drawing for the Evaluation Board is shown in Figure 27.
NOTE: A poor connection between the slug and ground increases junction temperature (TJ), which reduces the lifetime of the device. Evaluation Board Test Procedure
An Evaluation Board layer detail drawing is shown in Figure 28. Layer detail physical characteristics are noted in Figure 29. Table 5 provides the Bill of Materials (BOM) list for Evaluation Board components.
Step 1: Connect a +5 V supply to the VCC1, VCC2, VC_BIAS, VDET, and PA_EN pins. If available, enable the current limiting function of the power supply to 500 mA.
Circuit Design Considerations The following design considerations are general in nature and must be followed regardless of final use or configuration:
Step 3: Connect a signal generator to the RF signal input port. Set it to the desired RF frequency at a power level of –15 dBm or less to the Evaluation Board. DO NOT enable the RF signal.
1. Paths to ground should be made as short as possible.
Step 4: Connect a spectrum analyzer to the RF signal output port.
2. The ground pad of the SKY65165-11 has special electrical and thermal grounding requirements. This pad is the main thermal conduit for heat dissipation. Since the circuit board acts as the heat sink, it must shunt as much heat as possible from the device. Therefore, design the connection to the ground pad to dissipate the maximum wattage produced by the circuit board. Multiple vias to the grounding layer are required.
Step 5: Enable the power supply.
For further information, refer to the Skyworks Application Note, PCB Design Guidelines for HIgh Power Dissipation Packages, document number 201211. 3. Bypass capacitors should be used on the DC supply lines. An RF inductor is required on the VCC supply line to block RF signals from the DC supply. Refer to the schematic drawing in Figure 26 for further details.
Step 2: If desired, connect a voltage meter to the VDET pin.
Step 6: Enable the RF signal. Step 7: Take measurements. CAUTION: If the input signal exceeds the rated power, the SKY65165-11 Evaluation Board can be permanently damaged. NOTE: It is important to adjust the VCC voltage source so that +5 V is measured at the board. The high collector currents will drop the collector voltage significantly if long leads are used. Adjust the bias voltage to compensate.
4. The RF lines should be well separated from each other with solid ground in between traces to maximize input-to-output isolation.

Application Circuit Notes Center Ground. It is extremely important to sufficiently ground the bottom ground pad of the device for both thermal and stability reasons. Multiple small vias are acceptable and will work well under the device if solder migration is an issue. GND (pins 2, 9, 12, 13, and 16). Attach all ground pins to the RF ground plane with the largest diameter and lowest inductance via that the layout allows. Multiple small vias are acceptable and will work well under the device if solder migration is an issue. PA_EN (pin 5). Internal PA enable control pin for fast on/off control (on = +3 V to VCC; off = 0 to 0.5 V). VC_BIAS (pin 6). The bias supply voltage for stages 1 and 2, typically set to +5 V. RF_OUT1 and RF_OUT2 (pins 10 and 11). Amplifier RF output pins. Third stage collector voltage is connected to these pins through an output match circuit. Capacitor C28 should be placed as close as possible to the SKY65165-11. For 3.3 V operation, C29 should be placed 6.5 mm from capacitor C28. For 5.0 V
operation, capacitor C29 should be placed 7.0 mm from capacitor C28. Y1 and Y2 (pins 3 and 4). Interstage inductor input and output pins. N/C (pin 7). This pin is open and may or may not be connected to ground. VCC2 (pin 14). Supply voltage for the second stage collector bias (typically +5 V). To bypass VCC2, capacitors C8 and C16 (see Figure 7) should be placed in the approximate location shown on the Evaluation Board, although exact placement is not critical. VDET (pin 8). The power detector output voltage signal. This pin may be connected to PA_EN (pin 5). The benefit of this is that the current draw consumed by the detector will not be wasted with the device in the off state. VCC1 (pin 15). Supply voltage for the first stage collector bias (typically +5 V). To bypass VCC1, capacitors C5 and C15 (see Figure 7) should be placed in the approximate location shown on the Evaluation Board, although exact placement is not critical.

Functional Description The SKY65165-11 is a three-stage, HBT InGaP device optimized for high linearity and power efficiency. It contains all of the needed RF matching. An in-module active bias circuit is included within the device for all three amplifier stages, which provides excellent gain tracking over temperature and voltage variations. The first and second output stages are independently supplied using the VCC1 and VCC2 signals (pins 15 and 14, respectively). The DC control voltage that sets the bias for all three stages is supplied by the VC_BIAS signal (pin 4). The Evaluation Board includes shunt decoupling capacitors on these pins to suppress any possible bias affect on the RF signal at low frequencies. The SKY65165-11 includes an internal PA enable control pin (pin 5) for fast RF on/off control. Zero volts turns off the PA while 3 to 5 V enables the PA. The device also provides an output power detector voltage, VDET, at pin 8. Pin 1 is the RF input and pins 10 and 11 are the RF outputs. External DC blocking or RF matching is required on the RF output.
Grounding is through several ground pins and the package center ground. These features make the device suitable for wideband digital applications where PA linearity and power consumption are of critical importance (e.g., WLANs). The device has been characterized with the highest specified data rates for 802.11b (11 Mbps) and 802.11g (54 Mbps). Under these stringent test conditions, the device exhibits excellent spectral purity and power efficiency.
Electrical and Mechanical Specifications The absolute maximum ratings of the SKY65165-11 are provided in Table 2. The recommended operating conditions are specified in Table 3 and electrical specifications are provided in Table 4. Performance characteristics for the SKY65165-11 are illustrated in Figures 3 through 6.

DATA SHEET • SKY65165-11 POWER AMPLIFIER
Evaluation Board Description The SKY65165-11 Evaluation Board is used to test the performance of the SKY65165-11 PA. A typical application schematic diagram is provided in Figure 26. An assembly drawing for the Evaluation Board is shown in Figure 27.
NOTE: A poor connection between the slug and ground increases junction temperature (TJ), which reduces the lifetime of the device. Evaluation Board Test Procedure
An Evaluation Board layer detail drawing is shown in Figure 28. Layer detail physical characteristics are noted in Figure 29. Table 5 provides the Bill of Materials (BOM) list for Evaluation Board components.
Step 1: Connect a +5 V supply to the VCC1, VCC2, VC_BIAS, VDET, and PA_EN pins. If available, enable the current limiting function of the power supply to 500 mA.
Circuit Design Considerations The following design considerations are general in nature and must be followed regardless of final use or configuration:
Step 3: Connect a signal generator to the RF signal input port. Set it to the desired RF frequency at a power level of –15 dBm or less to the Evaluation Board. DO NOT enable the RF signal.
1. Paths to ground should be made as short as possible.
Step 4: Connect a spectrum analyzer to the RF signal output port.
2. The ground pad of the SKY65165-11 has special electrical and thermal grounding requirements. This pad is the main thermal conduit for heat dissipation. Since the circuit board acts as the heat sink, it must shunt as much heat as possible from the device. Therefore, design the connection to the ground pad to dissipate the maximum wattage produced by the circuit board. Multiple vias to the grounding layer are required.
Step 5: Enable the power supply.
For further information, refer to the Skyworks Application Note, PCB Design Guidelines for HIgh Power Dissipation Packages, document number 201211. 3. Bypass capacitors should be used on the DC supply lines. An RF inductor is required on the VCC supply line to block RF signals from the DC supply. Refer to the schematic drawing in Figure 26 for further details.
Step 2: If desired, connect a voltage meter to the VDET pin.
Step 6: Enable the RF signal. Step 7: Take measurements. CAUTION: If the input signal exceeds the rated power, the SKY65165-11 Evaluation Board can be permanently damaged. NOTE: It is important to adjust the VCC voltage source so that +5 V is measured at the board. The high collector currents will drop the collector voltage significantly if long leads are used. Adjust the bias voltage to compensate.
4. The RF lines should be well separated from each other with solid ground in between traces to maximize input-to-output isolation.

Application Circuit Notes Center Ground. It is extremely important to sufficiently ground the bottom ground pad of the device for both thermal and stability reasons. Multiple small vias are acceptable and will work well under the device if solder migration is an issue. GND (pins 2, 9, 12, 13, and 16). Attach all ground pins to the RF ground plane with the largest diameter and lowest inductance via that the layout allows. Multiple small vias are acceptable and will work well under the device if solder migration is an issue. PA_EN (pin 5). Internal PA enable control pin for fast on/off control (on = +3 V to VCC; off = 0 to 0.5 V). VC_BIAS (pin 6). The bias supply voltage for stages 1 and 2, typically set to +5 V. RF_OUT1 and RF_OUT2 (pins 10 and 11). Amplifier RF output pins. Third stage collector voltage is connected to these pins through an output match circuit. Capacitor C28 should be placed as close as possible to the SKY65165-11. For 3.3 V operation, C29 should be placed 6.5 mm from capacitor C28. For 5.0 V
operation, capacitor C29 should be placed 7.0 mm from capacitor C28. Y1 and Y2 (pins 3 and 4). Interstage inductor input and output pins. N/C (pin 7). This pin is open and may or may not be connected to ground. VCC2 (pin 14). Supply voltage for the second stage collector bias (typically +5 V). To bypass VCC2, capacitors C8 and C16 (see Figure 7) should be placed in the approximate location shown on the Evaluation Board, although exact placement is not critical. VDET (pin 8). The power detector output voltage signal. This pin may be connected to PA_EN (pin 5). The benefit of this is that the current draw consumed by the detector will not be wasted with the device in the off state. VCC1 (pin 15). Supply voltage for the first stage collector bias (typically +5 V). To bypass VCC1, capacitors C5 and C15 (see Figure 7) should be placed in the approximate location shown on the Evaluation Board, although exact placement is not critical.
