Due to the exponential growth of data communications, linearity specification is deteriorating
and, in high frequency systems, impedance transformation leading to power delivering from …

This paper presents a compact solution for impedance calculation obtained from low phase
resolution stationary wave measurements, for RF power systems operating in load varying …

This article presents an analysis of the effects of sampler characteristics and configuration
on impedance measurement performance with a sampled-network reflectometer. The …

In this paper, we analyse an antenna array fed with element-specific phase shifters and
amplifiers. The elements of the array are mutually coupled and the operation of the …

This paper studies the orthogonality in a directional modulation (DM) transmitter equipped
with an antenna array whose mutual coupling is considered. The antenna coupling will …

This thesis presents the application of multi-port reflectometry to radio-frequency (RF) power
amplifier (PA) output matching networks (OMNs). Power amplifier systems increasingly …
