Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings.

[0015] Such as figure 1 As shown, the millimeter-wave waveguide triplexer includes a waveguide second-power power divider 1, and the two output ends of the waveguide two-way equal-power power divider 1 are respectively connected to the waveguide two-way unequal power divider 2, the waveguide two-way unequal power divider 2, etc. The power splitter 1 divides the signal into two, and then adds a waveguide two-way unequal power splitter 2 with a distribution ratio of 2:1 at the two output terminals, and combines two ports with a distribution ratio of 1 to form a port , forming three-way waveguide output, the three-way waveguide output end is connected to the cavity filter, which are respectively the first cavity filter 4, the second cavity filter 5 and the third cavity filter 6, and the three cavity filters Metal diaphragms 7 are arranged at inner intervals, and the meta...

Abstract

The invention discloses a millimeter wave waveguide triplexer, which comprises a waveguide two-way equal power divider, two output ends of the waveguide two-way equal power divider are each connected with a waveguide two-way unequal power divider, one output ends of the two waveguide two-way unequal power dividers are combined into one output end to realize three-way waveguide output, and the three-way waveguide output end is connected with a cavity filter. The common work end of the waveguide two-way equal power divider and the two waveguide two-way unequal power dividers is provided with triangular protrusions. Metal diaphragms are arranged in the filter at intervals. The structure is simple, the isolation degree between multiplexer channels is improved, and the working bandwidth is increased.

Description

technical field [0001] The invention relates to a multiplexer, in particular to a millimeter wave waveguide triplexer. Background technique [0002] Multiplexers are often used in communication systems, and their main function is to select frequency and filter signals. In today's increasingly tight spectrum resources and increasingly complex electromagnetic environment, multiplexers are widely used in microwave communication, radar, satellite, electronic countermeasures and other systems because they can achieve filtering and frequency selection functions. [0003] The main principle of the multiplexer is to use multiple filters to separate multiple narrowband sub-signals in the signal according to the frequency band for subsequent processing, so as to reduce the broadband performance requirements of subsequent microwave devices and realize the function of "diluting" the signal. The filter and the multiplexer are part and whole. The filter is the basis of the multiplexer de...
