STUW81300T ST RF Synthesizer | 36-VFQFPN (6x6) | 0.25-6 GHz, 3.3V

Product Overview

The STUW81300T is a high-performance, wideband RF synthesizer from STMicroelectronics, designed for demanding wireless infrastructure and test equipment applications. It integrates a fractional-N PLL with a voltage-controlled oscillator (VCO) covering 0.25 to 6 GHz, offering low phase noise and fast settling time. Housed in a compact 36-VFQFPN (6x6 mm) package, it operates from a 3.3V supply and consumes only 250 mW typical. The device supports both integer and fractional-N modes, with a 24-bit modulus for fine frequency resolution. Its advanced architecture includes a programmable charge pump, integrated loop filter, and output dividers for flexible frequency planning.
