CMX90A009

10W 136 – 1000 MHz Power Amplifier

The CMX90A009 is a high efficiency single-stage GaAs HBT power amplifier in thermally enhanced 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.

Wide supply voltage range of 6 – 9.5 V make it suitable for 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, combined with CMX90A007 driver to provide a complete line-up solution. Support for complex modulation such as π/4 DQPSK and QAM can be achieved with CMX998 Cartesian feedback loop IC.
