Microstrip manifold coupled multiplexer

摘要

A multiplexer includes a microstrip manifold, and a filter bank having at least two output filters. The multiplexer channelizes an input radio frequency (RF) band of electromagnetic energy into a set of output channels by way of the filter bank. The microstrip manifold has an input port that receives an input RF signal, and at least two output ports. The microstrip manifold distributes the input RF signal to each output port, each said output port being coupled to a respective one of the at least two output filters. The multiplexer may be an input multiplexer for a spacecraft communications payload system.

1. A multiplexer comprising:
a microstrip manifold, the microstrip manifold including at least one planar conductive strip disposed on a non-conductive or dielectric substrate; and a filter bank, external to the microstrip manifold, comprising at least two output filters, wherein:
at least one of the two output filters is a cavity or dielectric resonator filter;the multiplexer is configured to channelize an input radio frequency (RF) band of electromagnetic energy into a set of output channels by way of the filter bank; andthe microstrip manifold has an input port configured to receive an input RF signal, and at least two output ports, the microstrip manifold being configured to distribute, by way of the at least one planar conductive strip, said input RF signal to each of said output ports, each said output port being coupled to a respective input of the at least two output filters.
