Coherent optical transceivers — first introduced to the market in 2008 — have proved to be a key technology for increasing data-rates of optical serial links. Most long-haul and metro optical networks...
RF/microwave filter design typically prioritizes high selectivity, sharp rejection, and flat in-band amplitude response. However, these features often cause large group-delay variations, which can sev...
5G mm-wave mobile handset transmission must comply with spectral mask limits set by regulatory and 3GPP standards. These are defined in terms of total-radiated-power (TRP), requiring measurements that...
This work proposes a low-loss digital-step attenuator (DSA) that covers the entire D-band (110-170 GHz) with a tuning range of 15.5 dB and a step of 0.5 dB. Utilizing a multi-stage reflective-type att...
Reliable high-fidelity qubit readout is essential for scalable quantum processors, with Josephson junction dynamics playing a decisive role in superconducting qubit architectures. This talk explores m...
