6300MHz miniature high-pass filter

Abstract

The invention relates to a 6300MHz miniature high-pass filter, which comprises an input port, an output port, three filter capacitors and two filter inductors, wherein the input ports are applicable to surface mounting, all elements respectively adopt the lumped parameter strip line design, and the structure is respectively realized by adopting the multilayer low-temperature co-fired ceramic process technology. The 6300MHz miniature high-pass filter has the advantages that the size is small, the insertion loss is small, the passband frequency extending is high, the weight is light, the reliability is high, the phase frequency characteristic linearity is good, the temperature stability is good, the cost is low, mass production can be realized, and the like, wherein the characteristic of small size has very important significance on the miniature study of a microwave system. The 6300MHz miniature high-pass filter is widely applicable to aviation, aerospace, individual electronic intelligent weapon, onboard and missile-borne wireless systems.

Description

Technical field [0001] The invention relates to a filter, particularly a 6300 MHz miniature high-pass filter. Background technique [0002] The continuous development of modern wireless communication technology has increasingly higher requirements for the performance of radio frequency modules.

Towards miniaturization. The laminated structure based on Low Temperature Co-fired Ceramic (LTCC) technology has the advantages of small size, low cost, simple struc...

AI Technical Summary

Problems solved by technology

Due to the large size of filters such as metal resonant cavities, microstrip line filters, block dielectric filters, etc., they cannot meet the requirements of miniaturization and frequency band extension; and the use of surface acoustic wave filter technology, although the volume can be reduced Small, but its electrical performance has the disadvantage of temperature drift, and the cost is high
