Description
The PHM020 is a 5 Watt FM / 1 Watt AM
amplifier module covering a bandwidth of
225-400 Mhz. It has a high harmonic rating
when operated in the AM mode. This dual stage
amplifier ia specifically designed for broad
band portable radio applications. External
Gate bias pin option is available upon request.
