Abstract
A low-phase noise 28.65 GHz oscillator has been demonstrated using a planar resonator. The resonator is micromachined close to the transistor and has an unloaded Q of 460. The oscillator uses a commercially available HEMT (Fujitsu FHR20X) for the active device, and results in an output power of 0.6 dBm with a 5.7% DC-RF efficiency. The measured phase noise is ¿92 dBc/Hz at a 100 kHz offset frequency and ¿122 dBc/Hz at 1 MHz offset. The micromachined oscillator required no manual tuning and has performance that is competitive with other hybrid, non-planar technologies such as dielectric resonator oscillators.
