<p>The present invention provides a small-sized oscillator facilitating the adjustment of a resonance frequency, permitting mass productivity to be improved, sufficiently suppressing the occurrence of a fundamental wave, and permitting cost reduction, and provides radio equipment using it. In this oscillator, an oscillation circuit is formed by providing a line (7) and a Gunn diode (6) on a dielectric substrate (3), a NRD guide as an output transmission line is formed by disposing a dielectric strip (5) between upper and lower conductor plates (1,2), and the above-mentioned line (7) 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 by the oscillation circuit is cut off, and that higher harmonic components are propagated. <IMAGE></p> |
