TRF372017SLWS224E –AUGUST 2010–REVISED JANUARY 2016
TRF372017 Integrated IQ Modulator PLL/VCO Features 3 DescriptionTRF372017 is a high-performance, direct up- Fully Integrated PLL/VCO andIQ Modulator conversion device, integratinga high-linearity, low-• LO Frequency from 300 MHzto 4.8 GHz noise IQ modulator and an integer-fractional• 76-dBc Single-Carrier WCDMA ACPRat –8-dBm PLL/VCO. The VCO uses integrated frequency
Channel Power dividersto achievea wide, continuous tuning rangeof
300 MHzto 4800 MHz. The LOis available as an• OIP3of26 dBm output with independent frequency dividers. The• P1dBof 11.5 dBm device also accepts input from an external LO or• Integer/Fractional PLL VCO. The modulator baseband inputs can be biased
either internally or externally. Internal DC offset• Phase Noise –132 dBc/Hz
adjustment enables carrier cancellation. The deviceis(at1 MHz, fVCOof 2.3 GHz) controlled through a 3-wire serial programming• Low Noise Floor: –160 dBm/Hz interface (SPI).A control pin invokes power-save• Input Reference Frequency Range: Upto modeto reduce power consumption while keeping
160 MHz the VCO locked for fast start-up. VCO Frequency Dividedby 1-2-4-8 Output
