Microwave Diplexer Purely Based on Direct Synchronous and Asynchronous Coupling [PDF]
Radioengineering, 2016 A diplexer realized purely based on direct coupling is presented. No cross-coupling is involved in the design process. The microwave diplexer is achieved by coupling a dual-band bandpass filter onto two individual channel filters.

Designs of Diplexing Power Dividers
IEEE Access, 2018 A diplexer with different-frequency power dividers cascaded to its output ports can split a signal into different frequency bands for power dividing functions. However, the design of a diplexer usually requires two different frequency filters. This paper presents three new microstrip diplexing power dividers (DPDs) to achieve duplexing power division ...

Design of New Eight-Channel Diplexer for Multiband Wireless Communication System
IEEE Access, 2018 In this paper, we proposed a new eight-channel diplexer (1.575/2.4/3.5/5.2 and 1.8/2.6/4.2/5.7 GHz) with a simple source-load input/output structure containing four pairs of coupled asymmetric stepped-impedance resonators (SIRs) in a compact circuit size.
