Embodiment Construction

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0031] An embodiment of the present invention provides a microstrip multiplexer. The microstrip multiplexer can not only combine multiple channels of narrow sub-band signals, but also combine multiple channels of wide sub-band signals. It is a A broadband multiplexer. Based on the embodiments of the present invention, multiplexers such as duplexers, triplexers, quadruplexers, and pentplexers, or wideband multiplexers can be designed, which have a simple struct...

Abstract

Embodiments of the present invention disclose a microstrip multiplexer, including a feeder, multiple microstrip filters, and a signal processing network. The multiple microstrip filters are separately connected to the signal processing network, and the signal processing network is connected to the feeder. Output signals of the microstrip filters of the multiple microstrip filters are combined by using the signal processing network and then output by using the feeder and / or a signal input from the feeder is split by using the signal processing network and then output to the microstrip filters. In the embodiments of the present invention, a wideband multiplexer that combines multiple wide subband signals for using can be implemented, and each subband has good frequency band response.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a microstrip multiplexer. Background technique [0002] With the development of communication technology, the communication system is becoming more and more complex, and the phenomenon of multiple receivers and transmitters working at the same time in the communication system is becoming more and more common. Multiplexer (Multiplexer) is an important device to realize multi-receiver and transmitter share one antenna to work at the same time, and has been widely used in many communication systems. For example, a duplexer (Duplexer) is a three-port device and is widely used in FDD (Frequency Division Duplexing, frequency division duplexing) systems. [0003] At present, the existing multiplexers all belong to the narrowband structure, and the multiplexers designed based on the existing structure are only suitable for occasions with narrow bandwidth, therefore, the common mul...
