TRF37x32 Dual Down Converter Mixer With Integrated IF AMP  
1 Features  
3 Description  
The TRF37x32 is a wideband dual down converter  
1
Device Family Supports Wide RF Input Range  
mixer with integrated IF amplifier. The device  
employs integrated baluns for single ended RF and  
LO inputs. The IF amplifier operates from 30 MHz to  
600 MHz in an open collector topology to support a  
variety of IF frequencies and bandwidths. The  
TRF37x32 provides excellent mixer linearity and  
noise performance and offers good isolation between  
channels for operation with diversity applications. The  
device operates with low power dissipation and  
further provides an option for a low power mode for  
power sensitive applications. Each channel can be  
independently powered down with fast response  
times to allow operation in time domain duplexed  
(TDD) applications.  
TRF37A32: 400 - 1700 MHz
