The MAX2042 is a single, high-linearity upconversion/down-conversion mixer that provides +36dBm IIP3, 7.3dB noise figure, and 7.2dB conversion loss for 2000MHz to 3000MHz WCS, LTE, WiMAXK, and MMDS wireless infrastructure applications.
The MAX2042 is a single‑chip, high‑linearity up‑conversion/down‑conversion mixer designed for wireless infrastructure applications such as WCS, LTE, WiMAX, and MMDS. It features a double‑balanced passive mixer core, an integrated LO buffer, on‑chip baluns, and supports both low‑side and high‑side LO injection.
The device is offered in a 20‑pin thin QFN‑EP package (5 mm × 5 mm) with an exposed pad, operates over –40 °C to +85 °C, and provides detailed electrical specifications including conversion loss, noise figure, IIP3, and supply requirements.
