23cm Power amplifier generating 20W of output with an input of 50mW making it ideal for use with our 23cm TX.
PCB incorporates a bias control to adjust the output power
with a 13.8V supply the amplifier is capable of about 30W, however this exceeds the recommended "safe" output power (refer to data sheet).
With an input of 50mW as per our 23cm TX the bias may be adjusted for an output of between 1 and 20W (refer to datasheet for operation beyond 20W).
