van Heijningen, M. (author), Ribeiro, D.C.A. (author), de Hek, A.P. (author), van Vliet, F.E. (author)This paper discusses the characterization of GaN transistors or MMICs under pulsed high-power stress and their recovery behaviour. A fully calibrated measurement setup is introduced where both forward and reflected waves are measured at input and output. In particular, also the effect of trapping due to the RF pulse on for example the insertion...conference paper 2022

(author)This article reviews the current state-of-the-art of active-integrated antennas co-designed with power amplifiers (PAs). Three strategies to improve output power and power-added efficiency are described using examples, namely direct matching between PA and antenna, tuning of harmonic reflections in the antenna, and in-antenna power combining...conference paper 2022

(author), van Vliet, F.E. (author)This paper describes a Ku-band up-converter for low cost satellite Machine to Machine (M2M) applications. The up-converter comprises a heterodyne sliding-IF architecture. This converts the baseband input signal (0 – 20 MHz) to the RF output signal (13.75 – 14.75 GHz). The necessary Local Oscillator (LO) signals are generated by an on-chip...conference paper 2020

(author)Solid-state power amplifiers need protection at the output to handle high reflections due to mismatch. Normally this is implemented by using a ferrite-based isolator. These are however large and bulky components.
