CMX90A009QK

SuRF RF from CML Microcircuits

Power Amplifier, 136 to 1000 MHz, 10W, 17 dB

Status: Featured | Data Sheet:

| RoHS Compliance: Rohs Compliant

The CMX90A009 is a high efficiency two-stage GaAs HBT driver amplifier in a thermally enhanced plastic DFN package, delivering +40.0 dBm (10W) 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 – 9.5V make it suitable for a variety of applications and enable 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, combined with CMX90A007 driver to provide a complete line-up solution.
