MAX2661

400MHz to 2.5GHz Upconverter Mixers

Maxim Integrated 

19-1382; Rev 1; 9/99

400MHz EVAFLOULALTOIWONDKAITTAMSAHNEUEATLS to 2.5GHz Upconverter Mixers

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.
