General Description

The MAX2660/MAX2661/MAX2663/MAX2671/MAX2673
miniature, low-cost, low-noise upconverter mixers are
designed for low-voltage operation and are ideal for
use in portable consumer equipment. Signals at the IF
input port are mixed with signals at the local oscillator
(LO) port using a double-balanced mixer. These
upconverter mixers operate with IF input frequencies
between 40MHz and 500MHz, and upconvert to output
frequencies as high as 2.5GHz.

These devices offer a wide range of supply currents and
output intercept levels to optimize system performance.
Supply current is essentially constant over the specified
supply voltage range. Additionally, when the devices are
in a typical configuration with V

SHDN

= 0, a shutdown

mode reduces the supply current to less than 1µA.

The MAX2660/MAX2661/MAX2663/MAX2671 are
offered in the space-saving 6-pin SOT23 package. For
applications requiring balanced IF ports, choose the
MAX2673 in the 8-pin µMAX package.
