In this work the influence of a car shape on the radiation characteristics of a roof mounted antenna is examined. Simplified roof geometries are designed to study the radiation characteristics of dipoles and a monopole at different positions. It is s

In this paper, authors present the preliminary measurements of a PWM-based transmitter. It is realised by cascading a pulse width modulator and a driver stage (PWCD), with a high efficiency Class E switched mode power amplifier (SMPA). The PWCD was r

We present a single-chip fractional-N PLL for space applications. The design employs a high-current charge pump with optimum output biasing and a low-current charge pump for extension of the tuning range. We show that the extension of the tuning rang

Broad band satellite communication makes high demands on linear low phase noise signals. One example is HDTV. For this application converters are required (e.g. from 30 GHz to 20 GHz), which themselves require very low phase noise programmable synthe

A nonlinear device modelling methodology capable of accurately predicting large-signal harmonic distortion in gallium nitride (GaN) HEMTs is presented. Harmonic balance simulation predicts the correct load target for maximum output power, with good a
