Wideband dual down converter mixer with integrated IF amplifier

The TRF37x32 is a wideband dual down converter mixer with integrated IF amplifier from Texas Instruments (TI). 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 device offers high mixer linearity and noise performance and offers suitable isolation between channels for operation with diverse 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.
