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.
