HF power amplifier 1200W VRF2933 8 pcs 1.8-30 MHz
HF power amplifier VRF2933 8 pcs folded in four power amplifier.
Addition of the four power amplifiers to create a highly reliable device with a combiner which not only adds uppower, but also divides the problem in the load.
Each of the four amplifiers feels comfortable.
Addition of a few power amplifiers is a good solution.
Making parallels transistors is a bad solution, but it is cheaper and easier.
