OSCILLATING SYSTEM BASED ON COAXIAL CERAMIC RESONATOR Russian patent published in 2016 - IPC H01P7/00 

FIELD: electricity.

SUBSTANCE: invention relates to microwave engineering and can be used in the composition of bandpass filters of receiving and transmitting devices and in the transistor active oscillators. In the proposed oscillating system based on coaxial ceramic resonator to eliminate equidistance of intrinsic frequencies, the coaxial ceramic resonator is configured jointed made of two pieces of coaxial lines with equal diameters of external and internal conductors, at that the sections are made of ceramic materials with different dielectric permittivities and equal electric lengths, one of the sections is short-circuited in the end, and interconnected open ends in the area of joint are galvanically connected by inner and outer conductors.

EFFECT: technical result of the proposed invention consists in possible design of small-size oscillating system with non-equidistant arrangement of undamped frequency for constructing the bandpass filters without parasite pass bands near odd values of frequency, multiple of low undamped frequency of resonator, and transistor active oscillators without spurious signals at odd harmonics of the main signal.
