Quad-Output LNA with AGC for  
Cable TV Applications  
General Description  
Features  
The MAX3558 broadband quad-output low-noise ampli-  
fier (LNA) is designed for digital set tops and digital ter-  
restrial applications. The LNA covers a 50MHz to  
878MHz input frequency range, while integrating a sep-  
arate automatic gain-control (AGC) function with over  
30dB of control range for each of four balanced out-  
puts. Each output has its own shutdown control to  
reduce power consumption when not used. The  
MAX3558 also includes a power detector that can be  
used to close the loop on any of the AGCs to prevent  
overload conditions. The LNA’s attack point is  
adjustable with an external resistor. The MAX3558 is  
available in a very small 28-pin QFN package with  
exposed paddle (EP).
