Texas Instruments TRF37x32 Wideband Dual Down Converter Mixers

Texas Instruments TRF37x32 Wideband Dual Down Converter Mixers include an integrated IF amplifier and employ integrated baluns for single-ended RF and LO inputs. The IF amplifier operates from 30MHz to 600MHz 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.

TRF37x32 EVM

Texas Instruments TRF37x32 Evaluation Modules (EVM) enables measurements of the TRF37x32 family of wideband dual downconvert mixers with integrated intermediate frequency (IF) amplifiers. The TRF37x32 family employs integrated baluns for single-ended radio frequency (RF) and local oscillator (LO) inputs. The IF amplifier operates from 30MHz to 500MHz in an open collector topology to support a variety of IF frequencies and bandwidths. Indicator components are located on the top side of the EVM to easily identify the component assembled on the board.
