Abstract

The present invention discloses a cavity resonator which has temperature stable compensating function. The resonator comprises a cavity, a resonance rod and a tuning screw bolt. The cavity is provided with a tuning screw bolt supporting structure and a resonance rod supporting structure. The resonance rod is fixed in the resonance rod supporting structure. The tuning screw blot is fixed in the tuning screw blot supporting structure. The tuning screw bolt supporting structure or resonance rod supporting structure is a boss structure. The axial variation of the outward extension of the boss structure in the invention fundamentally compensates the gross mount of the axial variation of the inward extension of the tuning screw bolt and the resonator thereby that the equivalent physical length of the resonance rod is sustained to be relative constant and the stability of the frequency is guaranteed.

Description

technical field [0001] The invention relates to a resonator, in particular to a cavity type resonator with temperature stable compensation function. Background technique [0002] In the early days of telecommunication development, filters played an important role in circuits, and have made continuous progress with the development of communication technology. In 1910, the emergence of a novel multi-channel communication system, the carrier telephone system, triggered a complete technological revolution in the field of telecommunications and ushered in a new era of telecommunications. The new communication system requires the development of a new technology that can extract and detect signals in a specific frequency band, and the development of this technology has further accelerated the research and development of filter technology. [0003] In recent years, a large number of technical engineers have discovered an important problem in the process of developing filters, that ...
