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 (1P3) is 17 dBm with a spurious free-dynamic range of more than 55 dB. © 2004 Wiley Periodicals, Inc.
