A K‐Band 4‐Channel Hybrid‐Packaged Phased‐Array Receiver With 1.6‐dB NF and 60‐dB Transmit Rejection

open access: yesElectronics Letters, Volume 61, Issue 1, January/December 2025.
The design utilizes WLCSP technology to integrate four GaAs LNAs and a 4‐channel CMOS beamformer into a single package for K/Ka‐band SATCOM. The GaAs IC features a 2‐stage self‐biased LNA and a 5th‐order band‐stop filter, achieving a low cascaded NF and high TX rejection.

Implicit common‐mode resonance by parasitic capacitances in LC oscillators for Ka‐band satellite receiver

open access: yesThe Journal of Engineering, Volume 2019, Issue 12, Page 8458-8462, December 2019., 2019
Parasitic capacitances in high frequency have a significant role in examining the inductor‐capacitor tank oscillators (LC oscillators) output signal quality. Here, the authors proposed a new idea for Ka‐band satellite receiver oscillator, which considers these parasitic elements, in order to maintain a specific precise frequency where there is no need ...

Active quasi circulator: Comprehensive review and performance comparison

open access: yesEngineering Reports, Volume 6, Issue 6, June 2024.
To cope up with the increased data transmission rate due to the modern multiband wireless communication systems, the three‐port circulator must be equipped with the ability to operate in different frequency levels while having adequate bandwidth. Thus, designing circulator as an antenna interface device becomes a challenging, particularly active‐quasi ...
