400MHz to 2.5GHz / Low-Noise / SiGe Downconverter Mixers
General DescriptionThe 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
Guidefor 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.

ABSOLUTE MAXIMUM RATINGS
DC ELECTRICAL CHARACTERISTICS(VCC= +2.7V to +5.5V, SHDN= +2V, TA= TMINto TMAX unless otherwise noted. Typical values are at VCC= +3V and TA= +25°C.
Minimum and maximum values are guaranteed over temperature by design and characterization.)
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.

Note 1:Guaranteed by design and characterization.
Note 2:Operation outside of this specification is possible, but performance is not characterized and is not guaranteed.
Note 3:Two input tones at -25dBm per tone.
Note 4:This spurious response is caused by a higher-order mixing product (2x2). Specified RF frequency is applied and IF output
power is observed at the desired IF frequency (70MHz).
