Abstract

Pilot frequency generator for teledistribution networks, which includes a voltage-controlled oscillator and a series of amplifying stages, formed by bipolar transistors, of which at least the second stage works in saturation, as a result of which its output level does not depend practically on the input level, thus guaranteeing the amplitude stability of the signal. This generator is used to provide a reference signal, stable both in frequency and in amplitude, to a series of teledistribution amplifiers.
