it's easy to put an attenuator between the output of the

I'm assuming you mean preselector - preamp.
At that frequency, they were usually made with a bipolar transistor,
unless it was custom made; then it could be a GaAs device. It is a
MRF-901 (or equivalent) if it is bipolar. Many times only 901
appeared on the device, if it wasn't ever changed.

I think you are confused Neal, the GaAs FET option was available on
GLB P/P 200 MHz and above. I did have them build me one for 2 meters,
