Abstract

The invention discloses a multiplexer structure based on a dielectrically integrated suspension line. The multiplexer is an N-multiplexer, wherein N is a positive integer greater than or equal to 2, the N-multiplexer comprises first to Nth band-pass filters, and each band-pass filter comprises a low-pass filter and a high-pass filter that are connected to each other; and when the multiplexer is aduplexer, one end of the second low-pass filter is the input end of the duplexer, the other end of the second low-pass filter is connected with the second high-pass filter and the first low-pass filter through a T-type junction, the other end of the second high-pass filter is a second output end, the other end of the first low-pass filter is connected with the first high-pass filter, and the otherend of the first high-pass filter is a first output end. According to the scheme, the problem of ensuring a high isolation degree between channels when the multiplexer receives and transmits signalsat the same time can be solved, and the mutual interference of the channels can be avoided.

Description

technical field [0001] The invention relates to the technical field of radio frequency microwave circuits, in particular to a multiplexer structure based on dielectric integrated suspension lines. Background technique [0002] With the rapid development of modern wireless communication technology, spectrum resources are increasingly tight, and real-time multi-directional communication in multi-channel communication systems is becoming more and more common. In a communication system, a multiplexer can separate or combine several radio frequency signals distributed in different spectral positions, and transmit them through a common antenna, and due to the reciprocity of the filter network, the multiplexer can play a role in the same device. Separating the function of transmitting and receiving frequency bands enables the transmitter and receiver to use the same antenna for transceiving, thereby reducing cost and volume, and reducing interference. The use of multiplexers is ve...
