Embodiment Construction

[0020] The present invention will be further introduced below in conjunction with the accompanying drawings.

[0021] The invention provides a segmented coaxial resonator tuning structure. Such as figure 1 As shown, this structure is used as the inner conductor of the coaxial resonator, which consists of two parts, the end and the base, and uses the same metal material. The end is as follows figure 2 , the base as image 3 shown. The aforementioned metal materials used to manufacture the structure of the present invention are preferably silver-plated aluminum, followed by copper.

[0022] The terminal head can be divided into an adjusting end 12 and an adjusted end 11 , and the base has a hollow tube 21 . The end and the base are combined together after being inserted into the hollow tube 21 along the adjustment end 12 in the form of a coaxial sleeve. The entire tuning structure is fixed on the coaxial resonator through the flange 22 at one end of the base, and the end w...

Abstract

The invention discloses a coaxial resonator tuning structure capable of reducing a micro discharging risk. The coaxial resonator tuning structure comprises an end socket and a base, wherein the end socket is divided into a tuned end (11) and a tuning end (12); the base is provided with a hollow pipe (21); and the size of an outer contour of the hollow pipe (21) is consistent with the size of the tuned end (11). The end socket and the base are sleeved coaxially to be arranged in a coaxial resonator so as to form an inner conductor and an outer conductor of the coaxial resonator. According to the invention, under the condition that the coaxial resonator is not disassembled, the frequency of the resonator can be tuned continuously, so that the coaxial resonator meets various requirements of high-power designs.

Description

technical field [0001] The invention belongs to the field of microwave coaxial filters and multiplexers that have clear requirements on micro-discharge thresholds, and relates to a coaxial resonator tuning structure that can reduce the risk of micro-discharge. Background technique [0002] In satellite communication systems, high-power filter devices are indispensable passive components. With the rapid development of the communication satellite business and the continuous advancement of science and technology, the capacity of the satellite load has been continuously enhanced, the available energy provided has increased, the efficiency has improved, and the transmission power has increased significantly. The requirements for the vacuum power bearing capacity of the filter components of the power amplification components are also higher. Especially in the L and S frequency bands in the form of coaxial resonators, micro-discharges are more likely to occur at low frequencies. ...
