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 OP1dB 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.
