Hi Vasile,

These are actually the units from M/ACom. They are careful to call them
"varactor controlled gunn oscillators" rather than traditional gunnplexors,
I was just using a shorter term. They are a gunn diode, varactor diode, and
a schottky (spelling?) mixer diode all together in a little package with a
waveguide flange as output. You can FM modulate the varactor rather than
the supply on the gunn. They have been used in a popular 2 megabit/sec
amateur radio wireless data link on the web, so it seems as though they are
capable of fast FM modulation and detection.

They are US $70 a piece, with a 10mW gunn diode, and for US $45 you can
replace that with a 100mW gunn.
