Reduce RF BOM and Footprint by up to 60% with STMicroelectronics' Newest RF Synthesizer with Embedded VCOs
The device allows lower cost and smaller footprint while increasing reliability for RF designers who want to manage synthesizers
Lexington, MASTMicroelectronics announced the STW81100 multi-band RF synthesizer with embedded VCOs (voltage controlled oscillators). Specifically, by leveraging the company's expertise in RF design and utilizing its world class BICMOS SiGe technology, designers were able to produce an integrated product that enables a lower bill of materials and uses a smaller footprint. This new product is the first in a series of highly integrated RF solutions integrating PLL and VCOs.
The STW81100 is a multi-band integrated RF synthesizer with VCOs for wireless communication and test equipment systems. Demonstrating high performance, high integration, low power, and multi-band capabilities, the device is a low-cost single-chip alternative to discrete PLL and VCO solutions which typically require two chips and are usually bulky and expensive. In addition, the device also leads to an indirect cost reduction as a one-chip approach increases reliability, reduces board space, reduces the number of external discrete components, simplifies sourcing, making it an overall more cost-effective solution.
The product includes an Integer-N frequency synthesizer and two fully integrated VCOs which feature low phase noise performance and a noise floor of -153dBc/Hz. The combination of wide frequency-range VCOs (thanks to center-frequency calibration over 32 sub-bands) and multiple output options (direct output, divided by 2, or divided by 4) allows the synthesizer to cover the 820MHz-1100MHz, the 1640MHz-2200MHz and the 3280MHz-4400MHz bands. It is also available as an IP cell, expanding the company's RF ASIC intellectual property (IP) portfolio.
"ST's tremendous RF capabilities and market leadership from handsets to infrastructure has translated into a family of products addressing the two main concerns from manufacturers today: lower BOM and smaller footprint," said Guillaume Pertinant, RF Technical Marketing Manager of ST's Wireless Infrastructure Division.
The STW81100 is supplied in a 28-lead exposed QFN lead free package and is priced at $3.00 in 10,000-piece quantities. Sample devices and evaluation boards are available now. Volume production will start mid-2005.
