Shokrolahzade, E. (author), Sebastiano, F. (author), Mubarak, F.A. (author), Babaie, M. (author), Spirito, M. (author)In this contribution, we describe the modeling approaches and the characterization procedures used to develop accurate standard models for cryogenic, probe-level, calibrations substrates.The key electrical and mechanical parameters of the impedance terminations and the lines used in commercially available impedance standard substrates are...conference paper 2023

Mortazavi, S.M. (author), Shen, Y. (author), Mul, D.P.N. (author), de Vreede, L.C.N. (author), Spirito, M. (author), Babaie, M. (author)This article presents an efficient digital polar transmitter (DPTX) at mm-wave frequencies that exploit a novel N -way series Doherty combiner (SDC) to enhance its drain and system efficiency at deep power back-off (PBO). The proposed N -way SDC is scalable and can be implemented elegantly using N transformers and N-1 shunt capacitors. As a...journal article 2022
