So what IS your point?...

But I must point out the resonant circuits in the output of the exciter. Usually the exciter has an output lowpass/harmonic filter. The practice in top-of-the-line FM systems these days is to use a harmonic filter on the exciter output only if/when it is used as a low-power transmitter directly on the air. Otherwise that filter is redundant, and can reduce the performance of the exciter by a small amount. RF |
