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

Active quasi circulator: Comprehensive review and performance comparison
Engineering 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 ...
