TRF37T05EVM Evaluation Module
This user's guide provides instructions for evaluating the TRF37T05 modulator with a TRF37T05EVM
evaluation module. The TRF37T05 is a quadrature modulator for up-converting the in-phase (I) and
quadrature-phase (Q) signals to RF signals in the transmit chain, typically used between the digital-to-
analog converter and the RF power amplifier.
