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 300 MHz to 4800 MHz. 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 start-up.
