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.
