Abstract :
A single-pole four-throw (SP4T) switch IC with a 3 dB bandwidth of over 50 GHz, which is believed to be the highest among cold-FET SP4T switches, is presented. A miniature and ideal divergence structure with an advanced four-level interconnect provides highly uniform performance in different paths.
