STW81200T STMicroelectronics | Wideband RF PLL Frequency Synthesizer - AICCHIP

Product Overview: STW81200T

The STW81200T is a highly versatile, dual-architecture (Fractional-N and Integer-N) RF frequency synthesizer manufactured by STMicroelectronics. Utilizing an advanced 0.25µm SiGe BiCMOS process, this high-performance IC integrates three low phase-noise Voltage-Controlled Oscillators (VCOs) with a fundamental frequency range of 3.0 GHz to 6.0 GHz. Thanks to its programmable dual RF output divider stage (divide by 1/2/4/8/16/32/64), the device offers an exceptionally broad output frequency coverage from 46.875 MHz up to 6 GHz. It optimizes both size and cost in end applications by integrating low-noise LDO voltage regulators and internally matched broadband RF outputs. Operating from a wide supply voltage range (3.0 V to 5.4 V) and fully configurable via an SPI interface, the STW81200T is the ultimate choice for cellular/4G infrastructure, CATV systems, satellite communications, and microwave point-to-point links. The "T" suffix indicates Tray packaging.
