Today, the editor will introduce a STW82100B, a highly integrated mobile communication base station chip from ST, in this article. The STW82100B series enables mobile infrastructure equipment manufacturers to meet market demands for more flexible and compact next-generation mobile network base stations at a lower cost. In addition to wireless base stations, it can be used in other equipment including radio frequency (RF) instruments and general wireless infrastructure applications.

In the mobile communication industry, consumer demand for broadband network services is growing rapidly. Mobile network operators are accelerating the rollout of network services with faster data rates (14.4Mbit/s or higher, HSPA/HSPA+). Investment in 3GPP-LTE, the next-generation wireless communication standard with higher speeds, has also continued to grow.

STMicroelectronics‘ STW82100B series meets the high-performance and low-cost requirements of equipment manufacturers, and integrates important mobile communication base station functions such as RF synthesizers and down-converters in a single chip. Market-proven, this IC is suitable for mobile communication standards such as LTE. Using STMicroelectronics‘ high-quality BiCMOS process, the STW82100B chip can also meet all the important performance requirements of mobile communication base station manufacturers. This chip from STMicroelectronics, which is manufactured on an advanced process, has been widely adopted by major base station manufacturers.

"The STW82100B series not only proves that using silicon germanium chips can effectively solve RF applications, but also shows once again the unlimited potential of ST‘s unique BiCMOS technology. BiCMOS process products have successfully entered various communication fields, such as providing high-speed transistors with speeds up to 230GHzFT/280GHz FMAX for optical fiber communication applications."

The STW82100B series (STW82100B, STW82101B, STW82102B and STW82103B) are based on ST‘s market-proven RF synthesizer ICs (STW81102 series) that are widely used in base stations and other wireless applications worldwide. Different working modes can be supported, giving designers a high degree of flexibility. On the receiver side, the chip provides a dedicated local oscillator (LO) frequency generator for each antenna channel, or can be used in more traditional antenna diversity systems. Within the transmitter loopback circuit, its excellent gain flatness and built-in 10-bit digital-to-analog converter (DAC) allow designers to achieve optimal signal calibration when driving external PIN diodes.

Main features of ST mobile communication base station chip STW82100B series:

1. High input linearity;

2. 8dB conversion gain;

3. 10.5dB noise figure;

4. Effectively avoid interference and false signals;
