A Voltage Controlled Oscillator/Mixer.
Abstract
A new technique for product mixing of an input signal with a locally generated reference by using a voltage controlled oscillator (VCO) is described and verified both mathematically and experimentally. The technique consists of frequency modulating the oscillator with the signal voltage. It is shown that for low-index frequency modulation by the signal, the sidebands of the oscillator produced by the signal are equivalent to those of a multiplicative mixer with a gain of approximately unity. The technique is particularly useful for synchronized IF correlator systems where a function generator can serve to generate the modulation waveform and act as a coherent detector simultaneously.
