SOE and Tyndall student awarded 2 prizes at the IEE International Microwave Filter Workshop 2024
SOE and Tyndall PHD student Steven Cheng received the 1st Place in the Best Student Paper Award for paper entitled “Multi-functional RF Filter with Co-Designed Low Noise Amplifier and RF Switching Capabilities” that was presented in the IEEE International Microwave Filter Workshop (IMFW 2024), Cocoa Beach, FL, U.S.A. Steven also received the PhD Initiative Award for the same conference.
Paper abstract “This paper presents a co-designed RF bandpass filter and low-noise amplifier (BPF-LNA) with quasi-elliptic transfer function and RF switching capabilities for sub-6 GHz communications. The BPF-LNA concept is based on complex[1]matched bandpass filtering matching networks (BPF-MN) that directly match the transistor impedances while at the same time achieving bandpass filtering; thus, eliminating the need for RF filters in the RF front-end. Frequency-dependent inter-resonator coupling elements are used in the BPF-MN to enhance the transfer function selectivity by means of transmission zeros (TZs). The concept has been validated at C-band through the design, manufacturing and testing of a BPF-LNA with fcen of 4.63 GHz, noise figure (NF) of 2.52 dB and one TZ at the lower side of the passband and a BPF-LNA with two symmetrically-allocated TZs and NF of 2.26 dB. By removing the DC biasing, the BPF-LNAs can be intrinsically switched-off with an isolation > 25 dB within an ultra-broad range”
Many congratulations to Steven and co-author and supervisor Professor Dimitra Psychogiou.
