The transition to fully digital mobile communications is increasingly complex with 5G and even more with 6G. Since transmitters largely determine system efficiency, they face the toughest challenges. ...
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...
Josephson Parametric Devices (JPDs), such as amplifiers and converters, emerged as essential building blocks and integral parts of modern superconducting quantum experiments operated in the GHz range ...
