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 >50 % 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. The measured data presented in this document is based on the evaluation board (EV90A007).
The wide supply voltage range of 6 – 9.5 V makes the CMX90A007 suitable for a variety of applications and enables 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.
