Global Wireless and Wireless Communication Semiconductor Innovation Solutions Leadership Broadcom is announced that BCM51030 devices with Versaline digital predistortion correction technology. This new solution can provide the industry's highest bandwidth support for wireless base stations and emerging HetNet RF applications, providing full features of the digital front-end (DFE) platform on a single chip, and can provide a bandwidth higher than the current solution Support to solve the problem of dispersion spectrum.
BCM51030 devices of Bo Tong use the company's innovative VersalineTM Digital Predictive (DPD) correction technology, which can accommodate wireless protocols (including 2G, 3G, and 4G signal combinations), power amplifiers, and frequency bands. This versatility enables wireless access network (RAN) original device manufacturer to quickly solve the dispersion spectrum allocation required by the global operator and different protocol combinations, and can also provide the industry's highest bandwidth support for the macro cell radio base station. The strongest power amplifier (PA) efficiency reduces power consumption of 80% 2. Conventional custom DFE requires a lot of optimization of the DPD algorithm for changes in each system variable to maintain acceptable bandwidth and power efficiency levels. In contrast, the ability of new equipment to quickly adapt to new technical agreements and new PA technology can reduce development time to months.
Analysts predicted that by 2016, the average wireless connection device of each person will reach six, which will result in an exponential growth in the wireless traffic, and the existing network constitutes a challenge, and the current and standardized spectrum resources will be More scarce. 4 Bo Tong's BCM51030 device can improve the work efficiency of the existing macro cell infrastructure, realize the spectrum multiplexing of non-adjacent honeycombs through small cellular, remote radiotele (RRH), and active antenna systems (AAS), and can provide more High bandwidth to meet the needs of the support for dispersion spectrum.
Market driving force:
• Upgrade to LTE and multi-mode operations require 2 × 2 or higher MIMO;
At present, 9 million users use LTE in 36 million mobile phones worldwide.
In 2016, there will be 15 million sets of macro base transceivers DFE channel shipments.
• Resolve the HetNet deployment of spectrum problems require scalability (2-16 + antenna, from low to high bandwidth)
Small honeycomb solutions to increase the multiplexing of the spectrum
• Require higher bandwidth to support dispersed spectrum and single RF equipment to reduce capital expenditure
The reason is the spectral shortage and the integration of different spectrum operators.
BCM51030 series products highlights:
• Can automatically adapt to any system of signal combinations, including MC-GSM, CDMA, WCDMA, LTE, and LTE-A
• Support any PA technology (AB, Dhadi Power, Envelope Tracking), and Transistor Architecture (LDMOS, GAS, GAN)
• TX and RX processing, including digital upper frequency conversion (DUC), amplitude factor attenuation (CFR), digital predistortion correction (DPD), and digital downconversion (DDC)
• The CFR and DPD send functions can maximize the power amplifier (PA) output, which will reduce delay to minimize
• Includes dual channels and four-channel devices, and can form 8-16 + channel systems via links
• Complete analog and digital monitoring systems with user programmable alarm responses, maximizing PA reliability
• Includes JESD204A / B serial interfaces to connect to the Number Converter (DAC) and analog-to-digital converter (ADC) to reduce the requirements of the signal and reduce power consumption.
Supply:
BCM51030 is currently being sampled, and the mass production time is scheduled to December 2012.
Boyong company executive introduction:
Higher Vice President and General Manager of the processor and wireless infrastructure department of Bo Jankov
"The more wide wireless bandwidth, lower power consumption, and scattered and scarce spectrum, the next-generation base station with revolutionary digital front-end technology and the demand for RRH, AAS and small cellular technology for the solution of the above problems. Boyong Company VersalineTMDPD linear BCM51030 devices provide original equipment manufacturers and operators with innovative products that are extracted in terms of bandwidth, power consumption, and versatility.
Joe Madden, chief analyst of mobile expert company
"With the deployment of LTE, mobile infrastructure RF equipment will require new scalability. In particular, multiple radio frequency channels will require MIMO and AAS signals. Further, due to carrier aggregation techniques and new LTE bands The instantaneous bandwidth of the mobile channel will increase by 4 times in the next two years. The market needs to be extended semiconductor chip solutions to handle multi-channel and various power levels of broadband carriers. Market is a system-level chip that supports Metrocell and Macrocell RF Demand will increase to hundreds of millions of dollars in the next four years.
