HF LINEAR POWER AMPLIFIER -500With1000With1KW-DIY-1.8-30mhZ- ROCKWELL COLLINS MODULE

  

With a bit of effort, you can turn this into a 500W linear power amplifier. You'll also need +12VDC, -12VDC, and +5VDC (you can use a power supply from an old desktop computer).

AN ADDITIONAL ALUMINIUM HEATSINK IS NOT REQUIRED----------. It will easily give you 500W CW (even more on SSB). These are new modules, but there may be soldering marks due to the testing process. A paper copy of the schematic will also be included in the package.

Don't overdrive the module and you'll see it performs exceptionally well. If you build a coupler/combiner, you can easily get 1kW output power from two modules. Be careful and double-check all voltage connections (through fuses, of course). The PTT switch should be connected to ground. There's no need to adjust the bias current, as the amplifier will come pre-adjusted. Feel free to ask if you have any questions. Have confidence - you will receive a perfectly working module.

The module is supplied without fans and without installed RF connectors.
