400MHz to 2.5GHz, Low-Noise,

SiGe Downconverter Mixers

General Description

Features

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.

ꢀ 400MHz to 2.5GHz Operation

ꢀ +2.7V to +5.5V Single-Supply Operation

ꢀ Low Noise Figure: 6.3dB at 900MHz (MAX2680)

ꢀ High Input Third-Order Intercept Point

(IIP3 at 2450MHz)

-6.9dBm at 5.0mA (MAX2680)

+1.0dBm at 8.7mA (MAX2681)

+3.2dBm at 15.0mA (MAX2682)

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.
