>>>The Mini-Circuits ERA-5+ MMIC is a single, pin head sized gain block that provides 20 dB of gain nearly flat out to 4 GHz with a 1 dB compression point at +18 dBm. It is 50 ohm in and out and works great on 12V. Three of these in series would make an extremely low component count, 60 dB gain block that is absolutely flat for the frequency range involved.<<<
Warren,
Both Jerry and I tried? that.? I use MAV11 a lower gain higher output part
and getting to oscillate in ubitx environment was trivial.? Getting non-oscillation
was very very difficult.? Jerry tried as a replacement for RV1 I tried at pre Q90,
and also as replacement for Q90.? Board layout was not friendly.
I did try the 2n6661 (VMOSfet) for the drivers and at first pass they were very good?
but most people would choke on the price ($15 ea).? Never tried BS170 or 2n7000
as those are fairly decent to 100mhz as wide band amps at moderate power.
