Abstract
An improved voltage controlled oscillator (VCO) is provided whereby the control voltage is utilized for modulation compensation by a modulation compensation network (90). The modulating signal is variably coupled into the voltage controlled oscillator (70) to compensate for the variation in the VCO's gain factor to yield a constant modulation level over a frequency band.
