Additive manufacturing of interdigital filters with arbitrary line cross section

Venter, J.J.P. (Johannes); Maharaj, Riddhi; Stander, Tinus (Institute of Electrical and Electronics Engineers, 2020-04)

This article investigates the novel use of additive manufacturing (AM) in the production of interdigital cavity filters. It is found that AM enables the production of interdigitated pins of complex cross-sectional geometry, ...
Characterization of diode-connected heterojunction bipolar transistors for near-infrared detecting applications

Venter, J.J.P. (Johannes); Sinha, Saurabh; Lambrechts, Wynand (Society of Photo-optical Instrumentation Engineers, 2018-11-08)

Please read abstract in the article.
Phase shifters with multiple independently controllable bands utilising frequency‐selective variable gain networks

Venter, J.J.P. (Johannes); Stander, Tinus (Wiley Open Access, 2021)

A dual‐band vector‐sum phase shifter with independent phase control of the 2.4 and 5 GHz Wi‐Fi bands is presented. The network uses band‐limited variable gain amplification, with a broadband hybrid coupler at the input ...
Transmission lines characteristic impedance versus Q-factor in CMOS technology

Venter, J.J.P. (Johannes); Franc, Anne-Laure; Stander, Tinus; Ferrari, Philippe (Cambridge University Press, 2022-05)

This paper presents a systematic comparison of the relationship between transmission line characteristic impedance and Q-factor of CPW, slow-wave CPW, microstrip, and slow-wave microstrip in the same CMOS back-end-of-line ...
X-band reflection-type phase shifters using coupled-line couplers on single-layer RF PCB

Venter, J.J.P. (Johannes); Stander, Tinus; Ferrari, Philippe (Institute of Electrical and Electronics Engineers, 2018-09)

In this letter, an X-band reflection-type phase shifter is presented. It is based on a single-layer stub-loaded coupled-line coupler loaded by two-varactor tuning circuits. This choice of coupler significantly improves on ...
