Thanks for the quick response. The circuit that they came out of had them in parallel with their bases grounded and +45 vdc on their collectors.
Looks like the RF came in through a tuned circuit on the emitter and went out via the collector. In that configuration they were producing 1000 watts at around 1Gig. The reason I was looking for a data sheet was to see if they could be used at a frequency between 3-30 Mhz. I’d be happy with 100 to 200 watts.
ok
yeah I havent been able to find any info either. With all my work in RF I would suspect that they are likely to be what is called "Controlled Q" devices that generally work over relatively narrow bandwidths maybe a couple of 100 MHz at the most.
(not all transistors are like that .... these ones may not be) But I would also hazard an educated guess that if they are designed for ~ 1GHz, I would be suprised if they would work at 3- 30 MHz mainly because of the internal makeup of the device to allow it to work at 1GHz without internal/self oscillation etc etc
I often come across some excellent devices that I would love to use on various Amateur radio bands but either because of lack of info like you have also found, or narrow bandwidth
I cant use them
edit.... ohhh and the other reason for the lack of info on some devices is cuz they were specifically built for a customer to their requirements and the manufacturer wont release info for the device
cheers
