Wideband phase modulator works directly on carrier
Abstract
Multiplier-induced problems related to undesirable effects of the varactor multiplier on the modulation spectrum are eliminated in a modulator circuit which operates directly at the desired output frequency. The principles of operation of the new circuit are discussed and attention is given to requirements for high-Q components and the possibility of linear frequency deviation.
