CMX90A009 10 W 136 MHz to 1000 MHz Power Amplifiers
The CML Micro CMX90A009 output power amplifier stage for two-way radio applications
The CML Micro CMX90A009 is a high-efficiency two-stage GaAs HBT driver amplifier in a thermally enhanced plastic DFN package, delivering +40.0 dBm (10 W) of output power with >60% efficiency at 435 MHz and 7.4 V.
CMX90A009 requires external matching at both input and output to optimize performance for each application and frequency band. A wide supply voltage range of 6 V to 9.5 V makes it suitable for a variety of applications. It enables direct connection to dual-cell lithium batteries, and on-chip active bias maintains operation over temperature.
CMX90A009 is intended as the output stage in a high-power amplifier and combines with the CMX90A007 driver to provide a complete line-up solution.
