The MAX2043 high-linearity passive upconverter or downconverter mixer is designed for UMTS/WCDMA, DCS, PCS, and WiMAX base-station applications, offering high linearity, low noise, and high component integration.
The MAX2043 high‑linearity passive mixer is designed for base‑station applications such as UMTS, WCDMA, DCS, PCS and WiMAX. It offers a wide RF range of 1700 MHz to 3000 MHz, LO range of 1900 MHz to 3000 MHz, and a DC‑to‑350 MHz IF range, with integrated baluns, a dual‑input LO switch and a double‑balanced architecture.
The device is supplied in a 36‑pin thin‑QFN package (6 mm × 6 mm) and operates from a single 5 V supply with a typical supply current of 108 mA. Key performance figures include +31 dBm IIP3, 7.5 dB conversion loss, 7.8 dB noise figure, and –52 dBm LO leakage, all guaranteed over –40 °C to +85 °C. This manual is written in Chinese.
