摘要：
This paper describes a packaged SiGe RF front-end design for use in the Unlicensed National Information Infrastructure (U-NII) bands. The front-end is based on a sub-harmonic direct-conversion architecture and is composed of an LNA, I and Q x2 sub-harmonic mixers (SHMs), and an LO conditioning chain. The receiver is completely differential and is designed for operation from a 3.3 V supply. Simulated performance shows >25 dB conversion gain, 6.8 dB noise figure (cascode LNA), 0degrees I/Q phase imbalance, and 39.1 mA total current consumption. To the authors' knowledge, this is the first 5-6 GHz SiGe active sub-harmonic direct-conversion receiver design presented in literature.
