Design of Bandpass Multiplexer-Integrated Power Dividers

This study proposed a novel methodology for designing bandpass multiplexer-integrated power dividers (PDs) that provide frequency division, selection, and division. New coupling schemes the PDs were presented to ensure multifunctionality compactness. Miniaturization was achieved through common resonator technique. Dual-mode stub-loaded resonators serving as various channel passbands used in PD reduce required number of thereby considerably size. Each passband can be individually designed using distributed technique decrease complexity. For validation, third-order triplexer-integrated quad-channel diplexer-integrated fabricated microstrip technology. Measurements devices consistent with simulated results. The circuits are compact, multifunctional, highly integrate, high performing, simple, easy fabricate; thus, they suitable practical applications, such multi-standard operation antenna array modules.
