AI Technical Summary
Technical Problem
Existing multiplexers suffer from significant metal and radiation losses and are not conducive to integration with other components such as detectors, leading to reduced performance.
Method used
Design a multiplexer with a conductive thin film layer on one side of a dielectric substrate, including signal lines and a ground plane. The connection structure and multiple bandpass filters are located on the same side. Through quasi-lumped resonant units and coupling connections, metal loss and radiation loss are reduced, and the process is simplified for easy integration.
Benefits of technology
It effectively reduces metal loss and radiation loss, improves the performance of multiplexers, simplifies the process, and promotes integration with components such as detectors.

Abstract
Provided in the present application are a multiplexer and a detector. The multiplexer comprises a dielectric substrate, a connection structure, and a plurality of band-pass filters having different operating frequencies. A conductive thin film layer is provided on one side surface of the dielectric substrate, and the conductive thin film layer comprises a signal line and a ground plate located beside the signal line. The connection structure is arranged on the side of the dielectric substrate provided with the conductive thin film layer, and comprises a main stem and a plurality of branches, the main stem being connected to all the plurality of branches, and the main stem serving as an input port of the multiplexer. The plurality of band-pass filters having different operating frequencies are all arranged on the side of the dielectric substrate provided with the conductive thin film layer, and are all connected to the signal line and the ground plate. Each of the plurality of band-pass filters comprises a first port and a second port, the first port being connected to the corresponding one of the plurality of branches, and the second port being one of a plurality of output ports of the multiplexer.
