HIGH FREQUENCY OSCILLATOR EMPLOYING DIELECTRIC RESONATOR

摘要

PROBLEM TO BE SOLVED: To provide in particular, a double harmonic wave oscillator which is enhanced in the frequency stability.;SOLUTION: In the high frequency oscillator wherein a high frequency transmission line interconnects an input and an output of a pair of oscillation amplifiers and an electromagnetic coupling body is provided between the input and the output of a pair of the oscillation amplifiers to form two oscillation closed loops for oscillating signals inverse to each other, the electromagnetic coupling body is configured to be at least a dielectric resonator. Further, the high frequency transmission line is a microstrip line having a signal line on one principal side of a board and having a ground conductor on the other principal side, and the electromagnetic coupling body is configured to use a slot line traversing the microstrip line and the dielectric resonator electromagnetically coupled to the slot line.;COPYRIGHT: (C)2005,JPO&NCIPI
