D.Ing. (Electrical and Electronic Engineering)
The various available unlicensed frequency bands around 60 GHz make the millimetre-wave (mm-wave) spectrum relevant for high-speed wireless data transfer. The continuous development in communication technology has supported wireless communication systems with higher operating frequencies. Filters are key front-end components in these communication systems. In a radio frequency (RF) receiver of a communication system, a bandpass filter (BPF) is used to allow in-band signals and to attenuate out-of-band signals sufficiently. High-quality BPFs are essential for the improvement of the overall performance of an RF receiver.
This research work entailed an investigation into mm-wave active BPFs with low loss, low noise and low power dissipation. The research showed that this could be achieved using a...
