A Proposal for a Low‐Frequency Axion Search in the 1–2 μ$\umu$ eV Range and Below with the BabyIAXO Magnet

Annalen der Physik, Volume 535, Issue 12, December 2023., 2023
This article describes the implementation of low‐frequency axion haloscope setups inside the future BabyIAXO magnet. The RADES proposal has a potential sensitivity to the axion‐photon coupling down to values corresponding to the KSVZ model, in the mass range between 1 and 2 μ$\umu$eV.

MXene Free Standing Films: Unlocking the Impact of Flake Sizes in Microwave Resonant Structures in Humid Environments

Small, Volume 19, Issue 37, September 13, 2023., 2023
This work presents a comprehensive investigation of MXene films operating as microwave resonators under varying humidity. The effect of MXene flake sizes on the resonant performance under varying humidities is experimentally studied. To mitigate the power losses of MXene films upon degradation (e.g., humidity exposure), an active feedback configuration

On‐chip GaAs‐based dual‐band bandpass filters/isolators (DBPFIs)

Electronics Letters, Volume 59, Issue 10, May 2023., 2023
MMIC co‐designed RF components exhibiting the collocated RF signal processing actions of a dual‐band bandpass filter and an RF isolator (DBPFI) are presented. They are based on in‐parallel cascaded bandpass filters/isolators that operate at two different frequencies and two multi‐resonant cells that are added in the RF input and RF output to increase ...

Analysis and design of a 10–20 GHz simultaneous noise and input matching low‐noise amplifier via frequency‐dependent negative feedbacks

Electronics Letters, Volume 59, Issue 3, February 2023., 2023
This letter presents a method for implementing a 10–20 GHz low‐noise amplifier with simultaneous noise and input matching performance by using a frequency‐dependent negative feedback network. The analytical equation of the required load is also derived for the first time in order to eliminate the Mille effect caused by the gate‐drain parasitic ...

An X/Ku band phase shifter with filter compensation technology

Electronics Letters, Volume 59, Issue 2, January 2023., 2023
This letter proposes an ultra‐wideband switched T‐type phase shifter, which covers the whole X/Ku band. The proposed switched T‐type phase shifter integrates a switched filter compensation structure, achieving a flat relative phase shift in broadband, which the conventional one cannot acquire.
