MAX2660/MAX2661/MAX2663/MAX2671/MAX2673
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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
