James, Check out www.rfparts.com They have several low power amps, 10mw to 7 W most likely you will need two amps to get to the 75 watt level Select one that is class AB & use an attenuator in between amps. Art, KC6UQH

Hello,
We are looking for a UHF amplifier (430-440MHz) for a transceiver to go from 10 mW to ~ 75W. Most of the amps were are funding require a much stronger input power than we can do. Note, it's a transceiver, so we want to be able to receive through the system as well. This is for half duplex satellite communication using a USRP radio.
Do you have any suggested amps?
Thanks,
