TRF3722 EVM User's Guide
TRF3722 is a high performance direct conversion quadrature modulator with exceptional linearity and low
noise performance. The TRF3722 converts low frequency baseband signals to high frequency RF signals
and integrates PLL and VCO to provide the local oscillator (LO) to the integrated modulator. This
document provides the operating procedures of the TRF3722 evaluation module (EVM).
