James, I do not see any amps that would meet your requirements. There are several intermediate types that would boost the 10mw@430mhz to enable you to use this low power driving another PA after that to meet 75watts output. It seems that you should invest in a "normal" mobile or handheld xcvr that would come closer to what you are trying to accomplish. Go to Mirage amps website for some specs on amplifiers to get a feel for what is commercially available. 73, Dee, NB2F

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,
