Abstract

PURPOSE:To stabilize the oscillation frequency, by coupling the resonator of high Q with the line, in the oscillator using the line. CONSTITUTION:The line 4 being the reactance load is connected to the gate electrode G of FET 1. The dielectric resonator 5 of high Q is coupled to the line 4. When the line 4 is viewed from the gate electrode G, at the resonant frequency of the resonator 5, the line 4 can be shorted at the coupling position and a reactance load is given to FET 1, but in other frequency, resistive load is given by the termination resistor connected to the line. Accordingly, when the oscillation frequency determined with the reactance load is in agreement with the resonant frequency of the resonator 5, the external Q of the oscillator can be several tens of times greater to establish the stable oscillator against the fluctuation in the bias voltage and temperature.
