DESCRIPTION
TRF372017 is a high performance direct up-conversion device, integrating a high linearity, low noise IQ
modulator and an integer-fractional PLL/VCO. The VCO uses integrated frequency dividers to achieve a wide,
continuous tuning range of 300MHz–4800MHz. The LO is available as an output with independent frequency
dividers. The device also accepts input from an external LO or VCO. The modulator baseband inputs can be
biased either internally or externally. Internal DC offset adjustment enables carrier cancellation. The device is
controlled through a 3 wire serial programming interface (SPI). A control pin invokes power-save mode to reduce
power consumption while keeping the VCO locked for fast startup.
