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.

Asynchronously coupled resonant junctions for diplexers and multiport filtering networks [PDF]

, 2017
This paper proposes the use of asynchronously coupled resonator junctions in the design of diplexers. This is to ease the control and implementation of the external couplings at the common port of an all-resonator-based diplexer.

A 130‐nm SiGe BiCMOS On‐Chip Diplexer With High‐Q Inductors for K/Ka‐Band Applications

International Journal of RF and Microwave Computer-Aided Engineering, Volume 2026, Issue 1, 2026.
This paper presents a high‐performance on‐chip diplexer designed for K/Ka‐band applications, fabricated via 130‐nm SiGe BiCMOS across two distinct frequency bands: 17–21 and 27–31 GHz. A localized backside etching (LBE) technique is employed to create air cavities beneath the inductors, a method that fundamentally mitigates substrate‐related losses and

Wideband Millimeter‐Wave Balun‐Diplexer Based on a Novel Coupled Marchand Architecture for Compact Footprint and Phased‐Array Integration

Microwave and Optical Technology Letters, Volume 67, Issue 11, November 2025.
ABSTRACT This letter presents the first reported wideband balun‐diplexer for mm‐wave applications, designed for shared‐aperture full‐duplex array systems. By integrating balun and diplexer functionalities in a single component, we enable per‐element self‐interference suppression, while also facilitating the interface between the balanced feed of the ...
