Abstract

A frequency multiplier (120) having a tunable resonant circuit (122), is anticipated for use with a frequency synthesizer (100) having a Voltage Controlled Oscillator (110). The VCO control line (116) voltage establishes the VCO (110) fundamental frequency (fo) as well as the resonant circuit (122) center frequency, such that the resonant circuit (122) frequency response will track a desired harmonic component within the multiplier output (130) even as the VCO control line (116) voltage and the fundamental frequency (fo) change in response to control line variation.
