Abstract

PURPOSE:To widen the variable range of an oscillating frequency by deciding the length of line so that the real part of an impedance viewing the end from a dielectric resonator is larger than the characteristic impedance. CONSTITUTION:The end of line of a strip line 2 coupled with the dielectric resonator 12 is brought into the state being not the matching end. The line of length between the dielectric resonator 12 and the end of the line 2 is decided so that the impedance viewing the end of the line 2 from the dielectric resonator 12 is larger than the characteristic impedance and the circuit is constituted that the oscillating frequency of the oscillator is decided by this system. The oscillating frequency is changed by changing the bias through the use of a control voltage -Vc.
