3 Description

The TRF37x32 is a wideband dual down converter 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.
