TRF3722 Quadrature Modulator

Texas Instruments TRF3722 Quadrature Modulator with Integrated PLL & VCO is a high-performance direct conversion quadrature modulator with exceptional linearity and low noise performance. The typical 0.25V baseband common-mode voltage supports a 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 provide excellent phase noise performance to satisfy the most stringent transmit communication requirements. The Texas Instruments TRF3722 also provides additional LO output for driving a second modulator or down-converting mixer. The modulator features a high gain mode for a typical 3dB gain increase and a low power mode when power optimization is desired.
