Abstract

The invention provides a production method for a Ku-band upper converter cavity filter. The method comprises the following steps of S1, sintering a circuit board, a chip carrier and an insulator on aconverter cavity; S2, carrying out eutectic operation on a bare chip amplifier and a chip capacitor to the chip carrier; S3, sintering related devices on the circuit board; S4, adhering an MEMS filteron the chip carrier; S5, bonding gold wires; and S6, covering and testing an assembled cavity patch assembly. According to the Ku-band upper converter cavity filter produced by the technology, through a test, high and low temperature experiments and whole machine debugging, various performance indexes reach a whole machine requirement. A technological process for producing the filter is scientific, simple and convenient. A product qualification rate of the production is greatly improved. Production cost is greatly reduced. Production efficiency is greatly improved.

Description

technical field [0001] The invention mainly relates to the technical field of manufacture of frequency converter modules, in particular to a manufacture method of a Ku-band up-converter cavity filter. Background technique [0002] In modern communication, due to the rapid development of wired, mobile and communication services, there is a phenomenon of frequency congestion in the low frequency band of microwaves, which can no longer meet the development of communication services. It is necessary to develop high frequency bands. Ku frequency band is an important frequency band of high frequency band. It has the characteristics of large transmission capacity, small external influence, high antenna gain and good directivity, and is often used for communication in ground communication stations. The up-converter converts the low-frequency signal into a high-frequency signal, and then transmits the signal through the power amplifier, thereby realizing the spatial broadcast of the ...
