Abstract

The invention discloses a miniature microwave quintplexer. The miniature microwave quintplexer comprises four low-pass filters, four band-pass filters, a high-pass filter and two matching networks, and is structurally achieved by the multilayer low-temperature co-fired ceramic process technology and by means of dielectric resonator hybrid. The miniature microwave quintplexer has the advantages of wide frequency coverage, low insertion loss, excellent isolation, light weight, small size, high reliability, good electrical property, good phase frequency characteristic linearity and the like, and is particularly applicable to occasions and corresponding systems such as communication with corresponding microwave frequency bands, digital radars and wireless communication handheld terminals with strict requirements on size, electrical property, temperature stability and reliability.

Description

technical field [0001] The invention relates to a multiplexer, in particular to a miniaturized microwave five-plexer. Background technique [0002] Microwave multiplexing filters are widely used in various military and civilian microwave systems. Its function is to divide a single signal into multiple signals of different frequencies, or to synthesize multiple signals of different frequencies into a wider signal. As a key microwave component in the channel transceiver system, the performance of the multiplexer directly affects the working status of the entire system. There are two general design methods for microwave multiplexers, which are formal network synthesis method and direct design method. The former is very complicated in actual application, and there are many restrictive conditions, so the practicability is not high. The direct design method is based on the known parameters of each branch filter, and realizes mutual matching between channels by adjusting existing...
