Abstract

We propose a simple, yet highly effective tuning method to increase the bandwidth of a waveguide voltage controlled oscillator (VCO) by applying controlled mechanical pressures to the packaged Gunn diode mounted in the waveguide cavity resonator. When we applied this method to a varactor-tuned, second-harmonic 94 GHz VCO, the bandwidth was doubled to 1 GHz with an output power over 14.8 dBm, which is suitable for frequency-modulated continuous-wave radar sensor applications.
