Abstract

We demonstrate 3-Gb/s wireless link using a 60-GHz receiver front-end fabricated in 0.25-μm SiGe:C bipolar complementary metal oxide semiconductor (BiCMOS) and a mixed-mode quadrature phase-shift keying (QPSK) demodulator fabricated in 60-nm CMOS. The 60-GHz receiver consists of a low-noise amplifier and a down- conversion mixer. It has the peak conversion gain of 16 dB at 62 GHz and the 3-dB intermediate-frequency bandwidth of 6 GHz. The demodulator using 1-bit sampling scheme can demodulate up to 4.8-Gb/s QPSK signals. We achieve successful transmission of 3-Gb/s data in 60 GHz through 2-m wireless link.
