A low power CMOS single-chip receiver and system-on-package for 60GHz mobile applications

Abstract

A low power single-chip CMOS receiver and system-on-package(SoP) in the low-temperature co-fired ceramic (LTCC) module for 60GHz mobile application are proposed. The single-chip receiver consists of a 4-stage current re-use LNA, C <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">gs</sub> compensating resistive mixer, Ka-band low phase noise VCO, high-suppression frequency doubler, and 2-stage current re-use drive amplifier. The size of the fabricated receiver using a standard 0.13¿m CMOS technology is 2.67mm × 0.75mm including probing pads. An RF bandwidth is 6.2GHz, from 55 to 61.2GHz and an LO tuning range is 7.14GHz, from 48.45GHz to 55.59GHz. The conversion gain and input P1dB are -9.5dB and -12.5dBm, respectively, at RF frequency of 59GHz. The proposed single-chip receiver describes very good noise performances and linearity with very low DC power consumption of only 21.9mW. The CMOS single-chip receiver and a LTCC 2×2 patch array antenna with 8.9dBi antenna gain compose the LTCC SoP module for 60GHz mobile applications.
