ADRF6755ACPZ

ADRF6755 is a highly integrated quadrature modulator, frequency synthesizer, and programmable attenuator. The device covers an operating frequency range from 100MHz to 2400MHz for use in satellite, cellular, and broadband communications. This modulator includes a high modulus, fractional-N frequency synthesizer with integrated VCO, providing less than 1Hz frequency resolution, and a 47dB digitally controlled output attenuator with 1dB 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 4.75V to 5.25V.

• I/Q modulator with integrated fractional-N PLL and VCO
• Gain control span 47dB in 1dB steps (VCC=5 V ± 5%, operating temperature range -40 to +85°C)
• Typical noise floor is -153dBm/Hz (I/Q inputs=0V p-p differential, attenuator setting=0dB)
• Typical nominal output power is −0.2dBm (VIQ=0.9 V p-p differential, -40°C to +85°C)
• Typical baseband modulation bandwidth is 600MHz (3 dB, -40°C to +85°C)
• Maximum frequency resolution is 1Hz (VCC is 5V ± 5%, -40 to +85°C)
• Typical gain flatness is ±2.0dB (Any 40MHz, -40 to +85°C)
• Voltage range from 4.75 to 5.25V (VCC1, VCC2, VCC3, and VCC4, -40 to +85°C)
• 56-lead frame chip scale package [LFCSP-VQ]
• Temperature range from -40°C to +85°C
