高功率低压GAAS HBT放大器
 |
ld体育下载RFMW宣布了CML微电路的两个MMIC功率放大器的设计和销售支持。这CMX90A003和CMX90A004是两个阶段，完全匹配的MMIC功率放大器，可在860 - 960 MHz，无许可频段中使用。高级GAAS HBT技术提供了高效率（49％PAE）和增益（30 dB）的组合。这CMX90A003is optimized for efficiency at low collector voltages (1.9 – 2.5 V) while delivering 29.5 dBm of saturated power, ideal as a booster PA for range extension of low-power transceivers, it’s suitable for systems with supercapacitor backup storage, thus extending the discharge period or battery life. The CMX90A004 is optimized for maximum efficiency at collector voltages of 2.7 – 4.5 V and intended as a final stage amplifier with 32.5 dBm saturated output power. |
