摘要： PROBLEM TO BE SOLVED: To reduce a rise time and/or a fall time of a dielectric resonator mounted oscillator circuit. SOLUTION: The dielectric resonator oscillator includes: a dielectric resonator 11; a drive circuit 20 for applying a resonance voltage to the dielectric resonator 11; a switch 71 for applying a voltage Vds required for generating the resonance voltage to the drive circuit 20; a switch 72 for applying a ground voltage for stopping generation of the resonance voltage to the drive circuit 20; and a capacitor 42 connected to a power terminal side that supplies the voltage Vds, as seen from the switch 71, for removing noise generated by the drive circuit 20. If these switches 71, 72 are made conductive exclusively, oscillation can be stopped immediately by turning on the switch 72. Since the capacitor 32 is in a charge storage state at all times, regardless of ON/OFF of the switch 71, the oscillation operation can be started immediately when the switch 71 is turned ON.

摘要： PURPOSE: To provide a magnetostatic wave S/N enhancer for which signal attenuation is small and to reduce burdens on an amplifier by making a saturation power threshold value for generating the power limitation effect of a magnetostatic wave filter different between a first magnetostatic wave filter and a second magnetostatic wave filter. CONSTITUTION: Signals inputted from an input terminal 1 are divided with the power ratio of 1:1 by a directional coupler 2 and the divided signals are inputted to the magnetostatic wave filters 3 and 4. In this case, the saturation power threshold value of the magnetostatic wave filter 3 is set at -25dB and the saturation power threshold value of the magnetostatic wave filter 4 is set at -5dB. Thus, the magnetostatic wave filter 3 performs a nonlinear operation because the power lamination effect works for the signal components above the saturation power threshold value of the signals inputted to the magnetostatic wave filter 3 and the magnetostatic wave filter 4 performs a linear operation because the power limitation effect does not work for the signals inputted to the magnetostatic wave filter 4. The passing signals of the magnetostatic wave filter 4 are converted to an opposite phase and then, synthesized with the passing signals of the magnetostatic wave filter 3 with the power ratio of 1:1 in the directional coupler 7.
