产品概述

The MAX2690 is a miniature, low-noise, low-power downconverter mixer designed for use in portable consumer equipment. Signals at the RF input port are mixed with signals at the local-oscillator (LO) port using a double-balanced mixer. The RF port frequency range is 400MHz to 2500MHz. The LO port frequency range is 700MHz to 2500MHz. The IF frequency range is 10MHz to 500MHz, provided the LO and RF frequencies are chosen appropriately.

The IF port is differential, which provides good linearity and low LO emissions, as well as providing compatibility with applications using differential IF filters, such as CDMA cellular phones. The mixer noise figure is 10dB at 900MHz.

The MAX2690 draws 16mA at VCC = 3V and operates from a +2.7V to +5.5V supply. A logic-controlled shutdown mode reduces the supply current to less than 1µA, making it ideal for battery-operated equipment. This device is offered in a miniature 10-pin µMAX package.
