The EVAL-ADRF6755SDZ is an evaluation board for evaluating ADRF6755 I/Q modulator. The ADRF6755 is a highly integrated quadrature modulator, frequency synthesizer and programmable attenuator. This I/Q modulator covers an operating frequency range from 100MHz to 2400MHz 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 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.
- Gain control span of 47dB in 1dB steps
- Output frequency range from 100MHz to 2400MHz
- Output 1dB compression of 8dBm at LO = 1800MHz
- Output IP3 of 20.5dBm at LO = 1800MHz
- Noise floor of -161dBm/Hz at LO = 1800MHz
- Baseband modulation bandwidth of 600MHz (3dB)
- Output frequency resolution of 1Hz
- SPI and I2C compatible serial interfaces
- 5V/380mA power supply
