Title: Edwin Van Der Heijden: Innovator in Radio Frequency Technology
Introduction
Edwin Van Der Heijden is a notable inventor based in Eindhoven, Netherlands. He has made significant contributions to the field of radio frequency technology, holding a total of 7 patents. His innovative work has paved the way for advancements in multiband radio frequency signal processing.
Latest Patents
One of his latest patents is a down-converter designed for receiving a multiband radio frequency signal and a local oscillator signal. This invention includes a frequency divider and a heterodyne receive chain. The frequency divider is configured to divide the local oscillator signal, providing different divided local oscillator signals. The heterodyne receive chain consists of a first stage mixer and second stage mixers. The first stage mixer mixes the multiband radio frequency signal with either the local oscillator signal or a divided local oscillator signal to generate a first intermediate frequency signal. Each second stage mixer then mixes the first intermediate signal with a divided local oscillator signal to produce second intermediate frequency signals that represent each band from the multiband radio frequency signal. The frequency divider ensures that each second stage mixer receives a different divided local oscillator signal.
Another significant patent is the fringe capacitor circuit, which implements capacitive circuits with desirable quality factors. In this embodiment, a fringe capacitor includes two capacitive circuits, each having a plurality of capacitive fingers extending from an end structure. These fingers are arranged in stacked layers, with vias connecting the fingers in different layers back to the connecting pins.
