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
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
Hi James.
That is a lot of gain. 10mW to 75W is around 38dB.
If I had this as a problem, I would consider putting two amplifiers together.
For example

But include a small amplifier 'brick' to get the drive up from 10mW.
Perhaps the M57721M from RF

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.
