The MAX2031 is a high-linearity passive upconverter or downconverter mixer designed to provide +36dBm IIP3, 7dB NF, and 7dB conversion loss for a 650MHz to 1000MHz RF frequency range to support GSM/cellular base-station transmitter or receiver applications.
The MAX2031 mixer is a double‑balanced passive device with an integrated LO buffer, SPDT LO switch, and on‑chip baluns. It supports both up‑conversion and down‑conversion modes, a 650 MHz–1000 MHz RF range, and a 650 MHz–1250 MHz LO range, making it suitable for GSM/base‑station transmitter and receiver designs.
The part is supplied in a 20‑pin thin QFN package (5 mm × 5 mm) with an exposed pad, operates from 4.75 V to 5.25 V, and draws less than 100 mA. Electrical performance is guaranteed from –40 °C to +85 °C, and the device is pin‑compatible with MAX2039/MAX2041 mixers for multi‑band PCB layouts.
