The MAX2029 is a high-linearity passive upconverter or downconverter mixer designed for GSM/cellular base-station transmitter or receiver applications.
The MAX2029 is a high‑linearity passive upconverter or downconverter mixer designed for GSM/cellular base‑station transmitter or receiver applications. It provides +36.5 dBm IIP3, 6.7 dB NF and 6.5 dB conversion loss over an 815 MHz‑to‑1000 MHz RF range and a 570 MHz‑to‑900 MHz LO range. The device integrates a double‑balanced mixer core, a dual‑input LO selectable switch, an on‑chip LO buffer, and RF/LO baluns for single‑ended inputs.
The part is supplied in a 20‑pin thin QFN package (5 mm × 5 mm) with an exposed paddle, operates from 4.75 V to 5.25 V supply, and is guaranteed from –40 °C to +85 °C. Electrical specifications, absolute maximum ratings, and typical performance curves are provided for both down‑converter and up‑converter configurations.
