TRF3722 Description
The TRF3722 is a high performance direct conversion quadrature modulator with exceptional linearity and low noise performance. The typical 0.25-V baseband mon 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.
