Abstract :
This paper discusses the development of a 25.5 GHz to 76.5 GHz single stage active frequency tripler for automotive radar applications. With an input drive level of 17 dBm at f/3, the frequency triplers tested demonstrated an output power level of 0 dBm from 73 to 82 GHz. The frequency tripler was subsequently cascaded with a 25.5 GHz VCO to demonstrate a 76.5 GHz VCO.
