Abstract

A monolithic 5.2‐GHz single‐ended‐in and single‐ended‐out Gilbert upconverter with balanced operation is demonstrated using 0.18‐μm deep n‐well CMOS technology. The fully matched Gilbert upconverter has conversion gain of −11.5 dB and OP~1dB~ of −19 dBm when input IF = 300 MHz, LO = 4.9 GHz, and output RF = 5.2 GHz. The IF input return loss is better than 14 dB for frequencies up to 7 GHz, while RF output return loss is 15 dB at 5.2 GHz. © 2004 Wiley Periodicals, Inc.
