Frequency from Carrier Center (MHz)
• 900MHz, 2.5GHz, 3.5GHz, and 5.5GHz BWA and W-CDMA Transistors • High Efficiencies for the Complete Product Family • Extensive Characterization under W-CDMA and OFDM Signal Personalities • Highly Correctable under Digital Predistortion • Reference Design under Class A/B and Doherty
Cree’s GaN HEMTs are ideal for high efficiency, high frequency, broadband, deployment being driven by high data-rate, multi-carrier networks. GaN HEMT transistors are well suited for tower mounted high power amplifier (HPA) applications, where small size and low weight
