Problems solved by technology

[0003] Generally, more single-core microwave insulators are installed on the shell of the T / R component, which not only complicates the welding process, but also takes up a lot of space
With the development of microwave components in the direction of high reliability, high density and light weight, on the basis of ensuring microwave performance, airtight performance and insulation performance, microwave insulators are required to have higher integration, smaller volume and lighter weight. But the current microwave components are still difficult to meet this technical requirement

Abstract

The invention discloses a circular device of a glass-sealed multi-core microwave insulator and a manufacturing method of the circular device, relates to the technical field of microwave devices, and solves the technical problems of low integration level, large size and heavy weight of the microwave insulator. The circular device comprises an outer conductor, an inner conductor and an insulator, wherein the insulator is a glass cylinder; N through holes are formed in the glass cylinder by 2-4 rows; the center distances between any two adjacent through holes are equal, and an inner conductor penetrates through the insulator from the through holes. Compared with the prior art, the integration degree is improved, the occupied space is smaller, the weight is lighter, the development requirements of aerospace and military radars for high reliability, high density, miniaturization and light weight are met, meanwhile, the cost is reduced, and the assembly process is simplified.

Description

technical field [0001] The disclosure relates to the technical field of microwave devices, in particular to a circular device of a glass-sealed multi-core microwave insulator and a manufacturing method thereof. Background technique [0002] Glass-sealed microwave insulators are often used in aerospace and military component systems with high sealing requirements, and are typically and widely used in radar T / R (Transmitter and Receiver, transmitter and receiver) components. Usually, the outer conductor of the microwave insulator is sealed and welded with the T / R component shell through solder paste, one end of the inner conductor of the microwave insulator is connected to the module circuit through gold wire bonding, and the other end is connected to the antenna socket to transmit microwave signals or The role of the feed port. [0003] Generally, more single-core microwave insulators need to be installed on the shell of the T / R module, which not only complicates the welding...
