Microstrip lowpass-bandpass diplexer topology
Electronics Letters, 1999 A new simple and effective topology for microstrip and planar lowpass-bandpass diplex filters is described that can exhibit high levels of isolation between the lowpass and bandpass ports. Two example diplexers have been designed and fabricated and the measurement results are presented.

Design Procedure for Interdigital Waveguide Bandpass Filters Based on Flat Metallic Strips
Radio Science, Volume 60, Issue 3, March 2025.Abstract In this work, we describe a new topology for interdigital bandpass filters implemented in waveguide technology. Compared to classical coaxial resonators, which are typically based on cylindrical metallic posts, the resonators that we propose are based on rectangular boxed cavities loaded with flat metallic strips of a finite thickness.

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.
