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.
