Based on the USRP specs (up to 100mW output power), I started looking around for amps that would get me up to a level comparable with other amateur rigs. This is one of the first I found:
http://shop.kuhne-electronic.de/kuhne/en/shop/amateur/leistungsverstaerker/MKU+PA+2M-120W+HY+VHF+MOSFET-Power+Amplifier/?card=632 Specs mention a low-pass filter so harmonics shouldn't be amplified. It takes 100mW in and puts out 120W on 2 meters. It needs up to 21A when running, that probably means getting quite a serious DC power supply or just running it off a car battery. It looks like it needs an external heatsink. Has anybody else tried solutions like this with USRP or other SDR transmitters? For simplex operation, if the application is not transmitting, will output power completely drop to zero when using something like this? Can anybody comment on how to wire the USRP and a power amp for TX and RX through a single antenna?
