ADRF6750:  950 MHz TO 1575 MHz Quadrature Modulator with Integrated Fractional-N PLL and VCO

Product Details

Product Status:Recommended for New Designs

The ADRF6750 is a highly integrated quadrature modulator, frequency synthesizer, and programmable attenuator. The device covers an operating frequency range from 950 MHz to 1575 MHz for use in satellite, cellular and broadband communications.

The ADRF6750 modulator includes a high modulus fractional-N frequency synthesizer with integrated VCO, providing better than 1 Hz frequency resolution, and a 47 dB digitally controlled output attenuator with 1 dB steps.

Control of all the on-chip registers is through a user-selected SPI interface or I2C interface. The device operates from a single power supply ranging from 4.75 V to 5.25 V.
