6–18 GHz Watt-Level Switchless Dual-Band PA MMIC using Coupled- Line-Based Diplexer

, 2018
In this work, a watt-level switchless dual-band power amplifier (PA) has been developed for multi-octave operation. To switchless dual-band operation, we proposed a new coupled-line based diplexer structure at the inter-stage and output-stage of the PA ...

A Compact K-/Ka-Band Diplexer with Dual-Mode Folded SIW Cavities

, 2022
The compact diplexer discussed in this paper is intended to feed a dual-band phased array for K-/Ka-band satellite communications (SatCom). Its filters at 20 and 30 GHz rely on a dual-mode cavity design in folded substrate integrated waveguide (FSIW ...

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 ...

Three‐Way Equal Filtering Power Divider for Modern Communication Systems

Engineering Reports, Volume 7, Issue 1, January 2025.
A balanced three‐way filtering power divider that receives input power and delivers equal amount of output to its three output ports is developed and realized using microstrip technology. The design is well‐suited for modern communication systems due to its low insertion and return losses, sharp selectivity, and integrated filtering capability ...

Novel microstrip diplexer for ultra-wide-band (UWB) and wireless LAN (WLAN) bands [PDF]

, 2013
A new microstrip diplexer for ultra-wide-band (UWB) and wireless LAN (WLAN) bands is presented in this paper. The proposed structure integrates a multipole directional filter operating at WLAN band coupled to a UWB filter.

Filter Design Using Ultra‐Miniaturised Substrate‐Integrated Coaxial Cavity

IET Microwaves, Antennas &Propagation, Volume 19, Issue 1, January/December 2025.
The proposed substrate‐integrated coaxial cavity (SICC) comprises two dielectric substrates with three metal layers. The top and bottom metal layers form the cavity's broadside walls, and the middle is a circular patch that shorts to the bottom wall and to an embedded split CPW ring, respectively, through a blind‐via ring and three blind vias.

Cross‐Polarisation Suppression in Self‐Diplexing Antennas

IET Microwaves, Antennas &Propagation, Volume 19, Issue 1, January/December 2025.
An approach to improve cross‐polarisation (XP) radiation in probe‐fed microstrip antennas is presented in this letter. The notable XP associated with self‐diplexing antennas caused by radiator multiplexing is discussed for the first time. In order to enhance the interport isolation and polarisation purity, the proposed antenna exploits the combined ...

Time transfer via single‐record TDoA measurements of GNSS satellites using direct cross‐correlation and relative pilot code phases

IET Radar, Sonar &Navigation, Volume 18, Issue 12, Page 2447-2453, December 2024.
A method is presented to passively synchronise data records via GNSS raw signals in a single record requiring only a GNSS antenna, an analogue‐to‐digital converter and computation hardware. The clock bias is estimated via the common view method with either full raw signal correlation or software‐based code correlation of individual signals from the GPS,
