The MAX9995 is a high-linearity dual-channel downconversion mixer with a frequency range of 1700MHz to 2700MHz, an input IP3 of +25.6dBm, and a noise figure of 9.8dB, making it suitable for WCDMA, TD-SCDMA, LTE, TD-LTE, and GSM/EDGE base station applications. This device integrates RF and LO port baluns, a dual-input LO selectable switch, an LO buffer, two double-balanced mixers, and a pair of differential IF output amplifiers. The MAX9995 requires a typical LO drive of 0dBm and supply current is guaranteed to be below 380mA. These devices are available in a compact 36-pin TQFN package (6mm x 6mm) with an exposed pad. Electrical performance is guaranteed over the extended temperature range, from TC = -40°C to +85°C.
The MAX9995 is a dual, high‑linearity downconversion mixer that provides 6.1 dB gain, +25.6 dBm IIP3, and 9.8 dB noise figure for a variety of base‑station applications. It integrates RF and LO baluns, a selectable LO switch, an LO buffer, and differential IF output amplifiers in a compact 36‑pin TQFN package.
Key features include a 1700‑2700 MHz RF frequency range, 1400‑2600 MHz LO range, 40‑350 MHz IF range, 50 dB LO1‑LO2 isolation, and a typical supply current below 380 mA. The device operates from –40 °C to +85 °C and is RoHS‑compliant.
