TRF3722 Datasheet (Texas Instruments)

TRF3722, Quadrature Modulator

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 (
