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.
