Abstract
A wideband, modulation sensitivity compensated, voltage controlled oscillator which automatically and continuously compensates over a wide bandwidth for modulation sensitivity variations resulting from changes in the center frequency of oscillation. The invention includes a compensation network which continuously varies the coupling between the modulation circuit and the oscillator tank circuit in response to changes in the steering control signal applied to a steering network. Continuous modulation sensitivity compensation is thereby provided over a wide bandwidth.
