TRF3705EVM Evaluation Module
This user's guide provides instructions for evaluating the TRF3705 modulator with a TRF3705EVM
evaluation module. The TRF3705 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.
