Abstract

PURPOSE:To achieve small size, stable frequency characteristics and mass production, by electromagnetic coupling between a microstrip line connected to the emitter of a transistor (TR) and a dielectric substance resonator. CONSTITUTION:An element corresponding to a capacitor C3 of a Colpitts type oscillator provided with a inductive element L between the collector and the base of a TR6, and capacitive elements C3, C4 between the base and the emitter and between the collector and the emitter, is a junction capacitor CBE between the base and the emitter of the TR6, and the element corresponding to the coil L is realized by a microstrip line 7 of open tip and with lambda/4-lambda/2 (where: lambda is wavelength of oscillation frequency) of length. The element corresponding to the capacitor C4 is a microstrip line 8 by electromagnetic coupling with a dielectric substance resonator 9 and of open tip and about lambda/4 length.
