3 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
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.
