General Description
The MAX2680/MAX2681/MAX2682 miniature, low-cost,
low-noise downconverter mixers are designed for low-
voltage operation and are ideal for use in portable com-
munications equipment. Signals at the RF input port are
mixed with signals at the local oscillator (LO) port using a
double-balanced mixer. These downconverter mixers
operate with RF input frequencies between 400MHz and
2500MHz, and downconvert to IF output frequencies
between 10MHz and 500MHz.
The MAX2680/MAX2681/MAX2682 operate from a sin-
gle +2.7V to +5.5V supply, allowing them to be pow-
ered directly from a 3-cell NiCd or a 1-cell Lithium
battery. These devices offer a wide range of supply
currents and input intercept (IIP3) levels to optimize
system performance. Additionally, each device features
a low-power shutdown mode in which it typically draws
less than 0.1µA of supply current. Consult the
Selector
Guide for various combinations of IIP3 and supply cur-
rent.
The MAX2680/MAX2681/MAX2682 are manufactured
on a high-frequency, low-noise, advanced silicon-ger-
manium process and are offered in the space-saving
6-pin SOT23 package.
