I'm looking for suggestions on UHF power amps. One of my stations uses a 10mw output SDR with a 2W gain block after it on TX. Right now I'm driving the 2W into a MIRAGE D26 to about 35W. I'd like to have about 100W. As I look at the various amateur power amps I'm not finding anything with 2W in and 100ish out. I could add some attenuation to the SDR/2W amp string and get the D26 output down to perhaps 20W to drive another power amp but that's not desirable because two amps in series creates a few problems.
I can find Minicircuits gain blocks that would get me to perhaps 10W, in place of the 2W gain block, then drive something like a D1010 but those are a bit steep at >$1,000....
So any ideas on how to get the SDR 10mw output up to about 100W would be appreciated.
Jim
