Schematic Rise

The following segment will provide the enhanced Motorola schematic for any typical application for the MRF141G (which includes parasitic stabilization features), a broadband power RF MOSFET which will place out a conservatively-rated 300 watts across the FM broadcast band. The flange about the MRF141G ought to be mounted to a heat spreader, a copper plate 5/16" thick and 6" x 8", which is then mounted to the heatsink with 6-32 machine screws, if your heatsink is drilled and tapped.

I recommend getting the two transformer assemblies, instead of trying to create them, due to the fact 15-ohm hardline is not straightforward to come across.
