High Frequency Power Generator

High Frequency Power Generator

(OP)
I am testing a board and need to generate 1 watt power at 100 KHz and 11 volts. Please advise.

RE: High Frequency Power Generator

100kHz, 11V, but what waveform?

If you need a sinusoidal output then most small audio power amps are capable of 100kHz if you adjust the deliberate high-frequency roll-off point. If you need a square wave then the harmonic frequencies required will be over 1 MHz, which is beyond the reach of most audio amps. You haven't provided sufficient information to answer your question.

I need the sinusoidal output

RE: High Frequency Power Generator

In addition to all the many other possible solutions, one could also build a simple Class A amplifier using a power FET as the active element. Neither 100 kHz nor 1 watt is challenging. Dead bug construction and adjustable PS, bias and drive. It should be straightforward.
