The MAX2470/MAX2471 are flexible, low-cost, high-  
reverse-isolation buffer amplifiers for applications with  
discrete and module-based VCO designs. Both feature  
differential 50outputs for driving a single differential  
(balanced) load or two separate single-ended (unbal-  
anced) 50loads. The MAX2470 offers a single-ended  
input and has two selectable frequency ranges of oper-  
ation: 10MHz to 500MHz and 10MHz to 200MHz. The  
MAX2471 offers a differential input and operates from  
10MHz to 500MHz. The MAX2470/MAX2471 also feature  
high input impedance for maximum flexibility, enabling  
them to be used with a variety of oscillator topologies.  
High reverse isolation combined with low supply current  
make them ideal for applications requiring high perfor-  
mance with low power.

Single-Ended (MAX2470) or Differential  
(MAX2471) Inputs  
These devices are also ideal for use as active baluns.  
The MAX2470 converts a single-ended input to a differ-  
ential output. The MAX2471 is useful as a differential  
buffer stage or to convert from a differential input to two  
single-ended outputs.

The MAX2470 operates from a single +2.7V to +5.5V  
supply. At -5dBm output power, it consumes 5.5mA in  
the hig h-fre q ue nc y ra ng e a nd only 3.6mA in the  
low-frequency range. The MAX2471 operates from a  
+2.7V to +5.5V single supply and consumes 5.5mA.  
Both devices are available in ultra-small SOT23-6 plas-  
tic packages, requiring minimal board space.
