The CMX90A007 is a high gain two-stage GaAs HBT driver amplifier in a plastic QFN package, delivering +33.5 dBm (2.2 W) of output power with >55 % efficiency at 435 MHz and 7.4 V.
CMX90A007 requires external matching at both input and output to optimize performance for each application and frequency band.
Wide supply voltage range of 6 – 9.5 V make it suitable for a variety of applications and enable direct connection to dual-cell Lithium batteries. The integrated active bias circuit and wideband interstage match ease design effort and minimize external components and PCB area.
CMX90A007 can be used as a stand-alone final stage PA or driver stage for the CMX90A009.
