Abstract
The present invention provides a small-sized oscillator facilitating the adjustment of a resonance frequency, permitting mass productivity to be improved, sufficiently suppressing a fundamental wave, and permitting cost reduction, and provides radio equipment using the oscillator. In this oscillator, an oscillation circuit is formed by providing a line and a Gunn diode on a dielectric substrate. An NRD guide serving as an output transmission line is formed by disposing a dielectric strip between upper and lower conductor plates, and the above-mentioned line and the NRD guide are coupled. The cut-off frequency of this NRD guide is determined so that the fundamental wave component of an oscillation signal from the oscillation circuit is cut off, so that higher harmonic components are propagated.
