OSCILLATOR AND COMMUNICATIONS DEVICE

摘要

Disclosed is an oscillator wherein, when adjusting the characteristics of the oscillator, the time-consuming removal of a cap and a substrate at each measurement is dispensed with, and which can be manufactured at low cost. The oscillator comprises a dielectric resonator, a circuit board, and an adjustment mechanism for adjusting the relative positional relationship between the dielectric resonator and the circuit board; the dielectric resonator having a dielectric substrate, electrodes provided on two opposite faces of the dielectric substrate, and electrode removal portions provided at predetermined positions on the electrodes; and the adjustment means comprising screws and springs for moving the dielectric resonator.
