STW81101ATR Description

Short technical summary and product information.

The STMicroelectronics STW81101ATR is a multi-band RF frequency synthesizer designed for high-performance wireless communication systems. It integrates dual differential VCOs with automatic center frequency calibration, covering frequency bands from 825 MHz to 4400 MHz through direct output and internal division options.

 

Key electrical specifications include a maximum frequency of 4.4GHz, an operating voltage range of 3V to 3.6V, and a typical fast lock time of 150 µs. The device boasts excellent integrated phase noise performance with a noise floor of -155 dBc/Hz. It supports SPI and I2C interfaces for digital communication.

 

Packaged in a 28-VFQFPN (5x5 mm) with an exposed pad, the STW81101ATR is designed for surface mounting. Its operating temperature range is -40°C to 85°C, making it suitable for various environmental conditions.

 

Applications for this frequency synthesizer include 2.5G and 3G cellular infrastructure equipment, CATV equipment, instrumentation, test equipment, and other wireless communication systems.
