This paper presents a new fundamental single‐balanced ring mixer incorporating T‐shaped compact microstrip resonant cells (TS‐CMRCs). The measured minimum single side‐band (SSB) down‐conversion loss of 3.3 dB is achieved for a 10.4‐GHz RF signal and is better than 6 dB from 9.6–11.5 GHz with a 0.1‐GHz IF. In addition, our working prototype demonstrates an excellent linearity response, in which the third‐order intercept point (IP3) is 17 dBm with a spurious free‐dynamic range of more than 55 dB. © 2004 Wiley Periodicals, Inc.
