Abstract
A 60‐GHz receiver front‐end with an integrated 180° out‐of‐phase Wilkinson power divider using standard 0.13 μm CMOS technology is reported.The receiver front‐end comprises a wideband low‐noise amplifier (LNA) with 12.4‐dB gain, a current‐reused bleeding mixer, a baseband amplifier, and a 180° out‐of‐phase Wilkinson power divider. The receiver front‐end consumed 50.2 mW and achieved input return loss at RF port better than −10 dB for frequencies from 52.3 to 62.3 GHz. At IF of 20 MHz, the receiver front‐end achieved maximum conversion gain of 18.7 dB at RF of 56 GHz. The corresponding 3‐dB bandwidth (ω~3 dB~) of RF is 9.8 GHz (50.8–60.6 GHz). The measured minimum noise figure (NF) was 9 dB at 58 GHz, an excellent result for a 60‐GHz‐band CMOS receiver front‐end. In addition, the measured input 1‐dB compression point (P~1 dB~) and input third‐order inter‐modulation point (IIP3) are −20.8 dBm and −12 dBm, respectively, at 60 GHz. These results demonstrate the adopted receiver front‐end architecture is very promising for high‐performance 60‐GHz‐band RFIC applications. © 2010 Wiley Periodicals, Inc.
