A 5.9-16.3 GHz agile tuning source using wideband millimeter wave MMIC circuits

An agile tuning voltage-controlled oscillator (VCO) assembly which covers a wide tuning range with a single control voltage has been developed. The VCO assembly achieved a frequency output of 5.9-16.3 GHz using a single silicon varactor over the tuning range of 0-20 V. The VCO assembly was realized by combining specially designed wideband millimeter-wave VCO/doubler, mixer, and dielectric resonator oscillator (DRO) monolithic microwave integrated circuit (MMIC) chips.<
