Product Description  
Class 1C ESD ( 1000V )  
Complete Solution in a Small  
3.2mm x 3.2mm, QFN Package  
RFMD’s RFSA2113 is a fully monolithic analog voltage controlled attenuator  
(VCA) featuring exceptional linearity over a typical temperature compensated  
30dB gain control range. The RFSA2113 features a wide bandwidth up to 18GHz.  
It incorporates a revolutionary new circuit architecture to solve a long standing  
industry problem: high IP3, high attenuation range, low DC current, broad  
bandwidth and temperature compensated linear in dB control voltage  
characteristic. This voltage controlled attenuator is controlled by a single positive  
control voltage with on chip DC conditioning circuitry. The slope polarity of the  
control voltage versus gain is selectable. The RFSA2113 draws a very low 2mA  
current. This attenuator is matched to 50Ω over its rated control range and  
frequency with no external matching components required. Typical VCA’s in this  
performance are based on compound semiconductor GaAs FET MMICs that  
require 1 to 2 negative voltages for control. This game changing product  
incorporates the complete solution in a small 3.2mm x 3.2mm MCM package  
that reduces the footprint in area and simplifies the control aspects over  
conventional compound semiconductor attenuator approaches.
