Abstract:The MAX2039 high-linearity passive upconverter ordownconverter mixer is designed to provide 7.3dB NF and a 7.1dB conversion loss for an RF frequency range of 1700MHz to 2200MHz to support UMTS/WCDMA,DCS, and PCS base-station transmitter or receiver
applications. In addition to offering excellent linearity and noise performance, the MAX2039 also yields a high level of component
integration. This device includes a double-balanced passive mixer core, a dual-input LO selectable switch, and an LO buffer. On-chip baluns are also integrated to allow for a single-ended RF input for downconversion (or RF output for upconversion), and single-ended LO inputs.
