The MAX2041 is a high-linearity double-ended passive converter from Texas Instruments. It adopts a double-balanced passive mixer core, supports single-ended RF input and single-ended LO input, and its working frequency range is 1700MHz to 3000MHz. It is an ideal choice for WCDMA, DCS, PCS and WiMAX base station transmitters or receivers.
The MAX2041 is a high‑linearity passive up‑converter or down‑converter mixer covering an RF range of 1700 MHz to 3000 MHz. It supports high‑side LO injection with an LO range of 1900 MHz to 3000 MHz and includes an integrated LO buffer, dual‑input SPDT switch, and on‑chip baluns.
The device is supplied in a 20‑pin thin QFN‑EP package (5 mm × 5 mm) and operates over –40 °C to +85 °C. Key performance figures include 7.2 dB typical conversion loss, +33.5 dBm input IP3, 7.4 dB noise figure, and a maximum supply current of 145 mA.
