Description for the TRF3722
The TRF3722 is a high performance direct conversion quadrature modulator with
exceptional linearity and low noise performance. The typical
0.25-V baseband common mode voltage supports seamless interface with current source DACs. The
device integrates the PLL and VCO to provide the local oscillator (LO) to the modulator. The PLL
and VCO provides excellent phase noise performance to satisfy the most stringent transmit
communication requirements. The device also provides additional LO output for driving a second
modulator or down converting mixer. The modulator features a high gain mode for a typical 3-dB gain
increase and a low power mode when power optimization is desired.
