Re: [Repeater-Builder] Falcon Communications MOSFET Power Amp
Eric: I remember Falcon Ads for these amps I think in both QST and 73 Magazine. There might have even been an article on them in 73 Magazine. There was a announcement of one of their amplifiers in the July issue of 1984 issue of ham radio. There was also an ad on page 24 of that same issue. I don't remember much about them, but I remember having a favorable impression about them. Not that helpful, but I can send you copies of the pages that I mentioned. Regards, Micheal Salem N5MS Eric Lemmon wrote: I have a 220 MHz rackmount power amp on the bench. The label states it was made by Falcon Communications of Newport Beach CA, and it is a MOSFET RF Power Amp, Model 4112A(?). The model number is smudged, so I can't be certain of it. The main PC board has two F1260 silicon VDMOS transistors working in parallel. These transistors are rated at 60 watts each, but I'm getting only 22 watts out with 5 watts input. There is a second PC board that controls the fan, but otherwise this is a single stage PA. I'd appreciate hearing from anyone who has knowledge of and/or tech data on this amplifier.

We have also never been able to get 100 watts out of it. The most is 70watts and the fets did not last. The fets may not be available now. They were hard to find and very very expensive. I would not recommend that amp. I have used a micor and it is much better. Cheers Doug VE5DA Yahoo!
