The MAX2690 is a low-noise, low-power downconverter mixer designed for use in portable consumer equipment. The device operates from a +2.7V to +5.5V supply and draws 16mA at VCC = 3V. It supports logic-controlled shutdown mode.
The MAX2690 is a 10‑pin µMAX package mixer that converts RF signals to a differential IF output. It operates from a single supply of +2.7 V to +5.5 V, draws 16 mA in normal mode and less than 1 µA in shutdown, making it suitable for battery‑powered equipment. The device covers a wide RF range (400 MHz‑2.5 GHz) and provides a low noise figure of 10 dB at 900 MHz.
Typical applications include ISM‑band radios, WLAN, PCS, CDMA, cellular phones and hand‑held radios. The datasheet includes absolute maximum ratings, electrical characteristics, pin descriptions, layout guidelines and statistical performance data.
