PA-47 Ready for Modification The new FET Leads will be bent to Accommodate the Existing PCB Holes |
The results at full power, are;
- With a 12.51 Volts DC supply running at 2050 ma (25.7 Watts DC Input with FAN)
- Exciter provides 12 mWatts Input at 10.140MHz
- The PA-47 output is 75 Volts PP RF measured at a 50 Ohm Load, which is: 14.1 Watts
- The HeatSink Temperature at the FET raised about 20 degree to 94.7 Deg F
This is a gain of 30.70dB and a Efficiency of about 66%.
I am a real Happy Camper !
Note: this is a very small 1 x 1.5 inch PCB, with a large CPU HeatSink.

I plan to re-layout the PCB to accommodate a Fan Control circuit and correct the small layout errors as explained on previous posts.

I'm noticing a pattern, I see a lot of cool homebrew projects that someone like myself would like to replicate, however you post no schematics. Please consider doing so in future postings. Thanks and 73, Jason W6IEE
