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 ...

Optimizing SiGe–SiO2 Visible–Short‐Wave Infrared Photoresponse by Modulating Interplay Between Strain and Defects Through Annealing

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 ...

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 ...

A compact 60‐GHz on‐chip bandpass filter in GaAs technology

Electronics Letters, Volume 60, Issue 7, April 2024.
A compact 60‐GHz on‐chip bandpass filter (BPF) is presented using gallium arsenide (GaAs) technology. The measurements show that it has a centre frequency of 60.2 GHz with a bandwidth of 14%, and the minimum insertion loss (IL) within the passband is 2.57 dB. The chip size, excluding the feedings, is about 0.265 mm × 0.184 mm. Abstract A compact 60‐GHz

Morphological Relaxation of Strained Epitaxial Films for Stripe‐Geometry Devices

Advanced Materials Technologies, Volume 9, Issue 4, February 19, 2024.
A new morphological evolution describing the relaxation of a strained epitaxial film deposited on a pattern with a stripe geometry is reported, paradigmatic of 2D like systems, and characteristic of transistors channels geometry. Both the elastic equation and surface diffusion equation are analytically solved, and reveal the different resulting ...
