A K‐band eight‐element reconfigurable phased‐array receiver with high Tx‐band rejection
IET Microwaves, Antennas &Propagation, Volume 18, Issue 12, Page 869-877, December 2024.Abstract A K‐band eight‐element phased‐array receiver is proposed, featuring a reconfigurable beam count and high Tx‐band rejection, tailored for satellite communication applications. By precisely designing the inter‐stage and output matching networks of the four‐stage low‐noise amplifier, the Tx‐band rejection of the receiver can be effectively ...

Advanced Photonics Research, Volume 5, Issue 8, August 2024.The beneficial effect of rapid‐like furnace annealing (FA) on photoconductive response of SiGe nanocrystals (NCs)‐based structures is revealed by comparison to rapid thermal annealing. FA structures present photocurrent spectra with enhanced intensity of peaks due to strain, explained by the short annealing time for NC formation without reaching ...
