This showed multipliers turned up in US surplus 39 Ghz radios. No data is available, but they measured them and even opened up a few. The units operate as x2, x3, and x4, best at x3, with an internal output amplifier in a range from  35 to 40 Ghz with over 10 mW out. Output is marked with a pencil on the distributed units and is around 16 <> 18.5 dBm. Usually used about +15 dBm Lo drive. Some work at +12, others at +18 best. They never lost a unit from overdrive. In use is an amplifier that can only go to +20 dBm drive. They lost several from exceeding the +5.7 volts.

There may even be a 2^nd harmonic on some, but hard to measure. The  harmonic mixers will multiply internally and make you think you have a  higher order signal. There are 3 styles, one large type and the other two types are smaller but identical with specifications.

The  different types  use + 9 volts, +12 and + 5.7 volts or +12 and + 9 volts. Don�t exeed the +5.7 and +9 volts. The +12 v drives the multiplier, and draws about 20 mA, the lower voltage is for the output amp, and draws about 100 to 150 mA. The small units are 1.8 in by 0.7 in by .3 inch. The large ones are 2.5 x 0.9 x 0.4 inch. All are marked with voltages.

They testing now them with 15.7 Ghz input. The 47.1 output is in the - 20 dBm range.  Guess useful for a weak signal (hi).There was an equivalent unit made for 49 ghz. Very rare. Maybe some will turn up in Europe. Above data is based on Will�s information and the text, found on the units.

73� and please give some info about your progression, off the distributed units.  Eene.
