The MAX9993 is a high-linearity down-conversion mixer that operates in the 1700MHz to 2200MHz frequency range. It is designed for UMTS, DCS, and PCS base station applications. The mixer provides 8.5dB of gain, +23.5dBm IIP3, and 9.5dB noise figure. It integrates baluns in the RF and LO ports, a dual-input LO selectable switch, an LO buffer, a double-balanced mixer, and a differential IF output amplifier. The MAX9993 requires a typical LO drive of +3dBm, and the supply current is guaranteed to be below 230mA. It is available in a compact 20-pin thin QFN package (5mm ✕ 5mm) with an exposed pad. The electrical performance is guaranteed over the extended -40°C to +85°C temperature range. The MAX9993 EV kit is available; contact the factory for more information.
The MAX9993 is a high‑linearity down‑conversion mixer designed for UMTS, DCS and PCS base‑station applications. It integrates RF and LO baluns, a dual‑input LO switch, an LO buffer, a double‑balanced mixer, and a differential IF output amplifier in a compact 20‑pin thin QFN package.
Key features include 8.5 dB conversion gain, +23.5 dBm third‑order intercept point, 9.5 dB noise figure, and a typical LO drive of +3 dBm. The device operates over a wide frequency range (RF 1700‑2200 MHz, LO 1400‑2000 MHz, IF 40‑350 MHz) and is guaranteed from –40 °C to +85 °C. This manual is written in Chinese.
