ADI ADRF6755ACPZ-R7

The ADRF6755 is a highly integrated quadrature modulator, frequency synthesizer, and programmable attenuator. The device covers an operating frequency range from 100 MHz to 2400 MHz for use in satellite, cellular, and broadband communications. The ADRF6755 modulator includes a high modulus, fractional-N frequency synthesizer with integrated VCO, providing less 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.
