Across multiple electronic application field, the leading global semiconductor maker STMicroelectronics (STMicroelectronics, abbreviation ST; the New York stock exchange code: STM) introduced a new high level of integration mobile base chip. New STW82100B series let mobile infrastructure equipment manufacturers can at lower costs more flexible and to satisfy the market the next-generation mobile network base station compact the demand. In addition to wireless base station outside, the new products are used to other devices, including radio frequency (RF) instruments and general wireless infrastructure applications.

In mobile communication within industry, consumer demand for broadband services are high growth. Mobile network operators are introduced to step up faster data rate (14.4 with Mbit/s or higher, HSPA +) HSPA/network services. The market the next generation of qualified for higher speed wireless communication standard 3GPP - the investment also continued growth LTE. City Infonetics true tone institutions show that by the end of the latest report by the end of 2014, LTE (long-term evolution technology) infrastructure market scale will more than $11 billion.

Stmicroelectronics new STW82100B series of high-performance with equipment manufacturers and low cost requirements, monolithic integrated radio frequency synthesizer and drop frequency converters important mobile base function. The market for this kind of IC verification, and in new mobile communication standards, such as LTE (long-term evolution technology). Adopts the high quality stmicroelectronics BiCMOS process, the new IC can also meet mobile base manufacturers all important performance requirements. Stmicroelectronics this model for advanced processing manufacturing base of chip has been mainly used extensively. Manufacturers

Stmicroelectronics network and storage products division Flavio Benetti marketing director, said: "STW82100B series products are not only proved using silicon germanium (SiGe) chip can effectively solve the problems, and rf application showed again stmicroelectronics unique BiCMOS technology. Unlimited potential stmicroelectronics adopts BiCMOS process products have successfully penetrated each telecommunication field, such as optical fiber communication application provides 230GHz FT / 280GHz at speeds as high as FMAX high-speed transistors."

STW82100B series (STW82100B, STW82101B STW82102B and STW82103B), with stmicroelectronics by market verification and by global stations and other wireless application widespread adoption of rf synthesizer IC (based STW81102 series). Can support different for designers working pattern, bring high flexibility. In the receiver, the chip can the for each antenna channel to provide a dedicated local oscillators (LO) frequency generator, or can be used for more traditional antenna diversity system. In the transmitter loop back circuit inside, its excellent gain flatness and built-in 10 digital-to-analog converters (DAC) let design personnel in the driver can be realized when external PIN diode best signal calibration.

STW82100Bs major features:

· high input linear

· 8dB conversion gain

· 10.5 dB noise figure

· effectively avoid interference and spurious signals

STW82100B has volume production, use 7 x 7mm VQFPN encapsulation, stmicroelectronics recently will launch application evaluation suite.
