• ADRF6704-EVALZ, Evaluation Board for the ADRF6704 provides a quadrature modulator and synthesizer solution within a small 6 mm + 6 mm footprint while requiring minimal external components. The ADRF6704 is designed for RF outputs from 2050 MHz to 3000 MHz. The low phase noise VCO and high performance quadrature modulator make the ADRF6704 suitable for next generation communication systems requiring high signal dynamic range and linearity. The integration of the IQ modulator, PLL and VCO provides for significant board savings and reduces the BOM and design complexity. The integrated fractional-N PLL/synthesizer generates a 2+ fLO input to the IQ modulator. The phase detector together with an external loop filter is used to control the VCO output. The VCO output is applied to a quadrature divider
