| Abstract | A passive CMOS downconversion mixer with LO buffer is presented in 0.25 mm SiGe BiCMOS using a 2.5 V supply. With a 60 MHz RF signal input, measurements show that the conversion loss is 2.9 dB, the input-referred 1 dB compression point is 20 dBm and the input-referred noise is 2146.8 dBm/Hz. Compared to conventional NMOS mixers, the 1 dB compression point is improved by 9.7 dB. The trade-offs and the design of the LO buffer, which has a strong impact on the intermodulation distortion, are also presented. Introduction: The presented passive CMOS downconversion mixer is part of a broadband power line front-end [1]. This analogue front-end employs a direct conversion receiver (centre frequency 2 MHz up to 60 MHz) with integrated tunable baseband filters (I/Q bandwidth 1, 2, 4 or 8 MHz). In this application, the received spectrum can |
