ADRF6703-EVALZ, Evaluation Board for Evaluating the ADRF6703 1550 to 2650 MHz Quadrature Modulator with 2100 to 2600 MHz Frac-N PLL and Integrated VCO

Description

• ADRF6703-EVALZ, Evaluation Board for the ADRF6703 provides a quadrature modulator and synthesizer solution within a small 6 mm + 6 mm footprint while requiring minimal external components. The ADRF6703 is designed for RF outputs from 1550 MHz to 2650 MHz. The low phase noise VCO and high performance quadrature modulator make the ADRF6703 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
