Abstract
Two types of self-injection locked NRD guide Gunn oscillators such as a reflection type and a band-stop type were investigated from the viewpoints of oscillation stability and injection locked range at 60 GHz. It was obvious that an effect of phase noise reduction of the reflection type was the same as that of the band-stop type, and that the injection locked range of the reflection type was more attractive than that of the band-stop type. The fabricated reflection type of self-injection locked NRD guide Gunn oscillator has a medium output power, measured to be 9 dBm at 59 GHz, and a low phase noise, measured to be less than -95 dBc/Hz for 100 kHz offset.
