MAX2031 is a high-linearity passive upconverter or downconverter mixer from Texas Instruments, designed to provide +36dBm IIP3, 7dB NF, and 7dB conversion loss for an 815MHz to 1000MHz RF frequency range to support GSM/cellular base-station transmitter or receiver applications.
The MAX2031 is a high‑linearity passive up‑converter or down‑converter mixer designed for GSM, CDMA, WCDMA, iDEN, WiMAX and other cellular base‑station applications. It operates over an RF range of 815 MHz to 1000 MHz with a 960 MHz to 1180 MHz LO range for high‑side injection, and includes an integrated LO buffer, SPDT LO switch, and on‑chip baluns.
Key specifications include +36 dBm IIP3, 7 dB conversion loss, 7 dB noise figure, and a supply current below 100 mA. The device is offered in a 20‑pin thin QFN package (5 mm × 5 mm) with an exposed paddle and is rated for –40 °C to +85 °C operation. Ordering information and detailed electrical characteristics are provided for designers.
