The RM HLA 150V Plus uses two MRF 455 RF power transistors in a parallel push pull circuit biased in class AB. There are 6 Low Pass Filters to reduce harmonic output that may be selected manually or automatically. TX/RX switching can be automatic using RF sense or via external PTT input.

Two variable speed fans mounted on top of the heatsink keep the amplifier cool even under intense operation such as in contest use. The amplifier’s protection circuit will warn you about over heating, too much drive power and SWR above 2.5:1.
