Abstract :
The 94 GHz waveguide VCO using InP Gunn diode was designed and fabricated. The fabricated VCO has excellent linearity of 1.7 % at 680 MHz bandwidth and power flatness of 0.68 dBm, respectively. The LPF is designed under -40 dB at 47 GHz and the resonator is designed for frequency generation at 47 GHz. From the measured results the fabricated waveguide VCO has excellent performances: the bandwidth is 1365 MHz at 93.98 ~ 95.345 GHz and the output power range is from 14.78 dBm to 15.46 dBm. The phase noise is under -100 dBc / Hz at 1 MHz offset.
