Abstract:A high performance, W-band 2nd harmonic Gunn oscillator has been developed. A common waveguide cavity is designed for both the fundamental and 2nd harmonic frequency, Mechanical tuning range is up to 15GHz(100-115GHz), output power is over 5mW and maximum output power is 18.5mW. The linear electronic tuning range is more than 250MHz. This VCO has been used in 2.6mm wave band phase-lock local system of large millimeter wave radio telescope of PMO.
Keywords:Gunn diode  Fundamental frequency  2nd harmonic frequency  Oscillator  Radialline
