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

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 ...

Revenue Management to Maximize Global Network Revenue for a Satellite Communication Operator
International Journal of Satellite Communications and Networking, Volume 43, Issue 5, Page 369-380, September/October 2025.ABSTRACT The satellite communication (SatCom) industry is rapidly expanding, with supply growing much faster than demand, potentially straining market prices and company stability. Effective revenue management (RM) can help operators optimize the use of limited and expensive satellite resources.

Distributed remote antenna unit with selection‐based of (RoF‐IoT) paradigm: Performance improvement
IET Communications, Volume 19, Issue 1, January/December 2025.Abstract Mixing the wireless medium with fiber optics can form a new communication system called a radio‐over‐fiber (RoF) network; it is a promising solution that can provide high bandwidth and a reliable connection between numerous sensors in wireless sensor networks (WSN) and the central office (base station) within a particular area.

Another Giant Leap: 50 Years of Military Satcom
Air and Space Power Review, 2022 The story of human exploration of space tends to capture the imagination but there has been a distinct lack of study into the Royal Air Force’s own history of space operations.

Artificial Intelligence for SatCom Operations
, 2020 Artificial Intelligence (AI) might become a crucial element for satellite communications (SATCOM) operations. Procedures based on AI techniques are meant to reduce the human intervention in all space operations value chain and, consequently, reduce the operational expenditures of the overall satellite systems.
