Publikováno v: Microwave and Optical Technology Letters, 59(2), 388-393. Wiley

This letter reviews the design procedure of a high‐speed Schottky video detector for high‐data‐rate communications within the ultra‐wideband (UWB) frequencies. The classic design approach for video detectors is extended with a mixer‐like an
