“All Things are Connected”is coming, Kangxi Communication is going upwind


Kangxi communication announced the launch of a silicon based fully integrated NB-IoT/LoRa RF front-end IC KCT8101L today

There is a growing demand for mobile communication, video transmission, or terminal applications, where the Internet is ubiquitous, so even if 4G continues to expand, 5Gs generation is about to come, and the business opportunities are limitless in it. With the rapid development of the industry, the diverse application needs of the users are increasing. In the face of the increasing demand for data transmission speed and network capacity of global users, 5G network came into being. By 2020, it is expected that the related products will enter the commercial stage. In the future, it will not only need a large transmission rate, but also a number of times larger than the current number of links, the world will enter the era of everything connecting. According to authoritative organization data, 2016 China Internet of things industry scale reached RMB 900 billion, compound growth rate reached 25% in the period of 2011-2015, through the network machine to machine connection number through 100 million, occupying 31% of the worlds total. Mckinsey, a well-known consulting firm, pointed out that the application value of IoT in 2025 will reach $11.1 trillion. 5G put forward low delay, high transmission and low energy consumption, big junction and other characteristics, 5G mobile communication is expected that in 2020, the world will have 50 billion terminal products with access to the Internet, the overall system capacity demand is also increase 1000 times than 4G, and its transmission delay must be less than 1 milliseconds, so the next generation of 5G communication efficiency and technical challenges are bound to be more severe than before. With the emergence of smart meters, smart appliances, smart factories and wearable devices, more and more work and life need to be solved through the intelligent terminal. For this, high density links and lower end cost requirements are becoming larger and larger, and there is a need for new technologies to cope with such requirements. In the future development of 5G, the goal of terminal design mainly includes : lower cost of equipment, lower power consumption, greater coverage and support for a large number of equipment connections. In this context, a technology with lower transmission data, lower cost of equipment, and wider coverage is known as NB-IoT ( Narrowband-Internet  Of  Thing ) stands out, its maximum transmission data amount is 200kbit/s, bandwidth also drops to 200kHz, and its coverage rate can be increased several times. In 2016, NB-IoT ecology is rapidly shaping up with an overwhelming trend. As a great tool to deal with the challenges of the new era of the Internet of Things, NB-IoT will lead to the revolution of the Internet of Things change, the achievement of the new era of the Internet, the great opportunity for all walks of life. After the establishment of NB-IoT standard, it is of great significance to the development of the Internet of Things. The industry believes that NB-IoT will account for 70% of the total application of the Internet of Things. It will not only activate many stock markets ( such as smart meter reading is expected to add about 50 million per year ), but also in emerging applications such as smart parking and wearable markets, outdoor sports, health testing, home control and other markets will increase the connection of NB-IoT applications, will drive the entire Internet of things market rapid development. With the gradual formation of 2016 standards, 2017 NB-IoT will usher in the commercial scale of the important node, becoming the next 1 trillion market to compete.

Market demand for RF front-end chips and pain points

At the present stage, 5G from the concept of research has entered the substantive promotion phase, and RF front-end chip as the core equipment of the Internet of Things, all hardware and software in the Internet of things are in an irreplaceable position, RF front-end chip product market also has broad prospects, high performance, low cost, high reliability of the product solution is able to quickly open the market, become the key to seize the market opportunity. With the rapid development of the Internet of Things chip market, but also have following five aspects of the higher application requirements to the current RF front-end solutions: 1, the product low power consumption, the application of the Internet of Things is different from the Internet. It has high demand for low power consumption, such as handheld devices, offline acquisition and so on. The battery can be required to support the terminal module for 5-10 years; 2, the high performance of the product, namely the realization of high power and low delay, auto driving, remote operation and other business end to end delay requirements of 1 Ms, while the smart meter reading system requires deep coverage; 3, the low cost of the product, most of the functions of the Internet of Things device are single, and the application of diversification is very sensitive to the cost of the chip. Generally requirements that chip price is $1~$2, the cost of the terminal is less than $5; 4, the high integration of product, high integration solution can effectively reduce the cost of the system, and greatly reduce the cost of product development. In addition, the miniaturization of the high integration scheme has also opened up a large number of wireless sensors and other applications. 5, a mature and reliable solution, the Internet of Things market rapid growth, not only need manufacturers have the ability to provide high performance of popular products, more important is a mature and reliable solution, that can help customers to quickly launch innovative products.


In this huge domestic and international market demand background, KangXi communication announced the introduction of silicon based fully integrated low-power NB-IOT RF front-end chip KCT8101L in February 2017. KCT8101L use Kangxi’s unique Silicon-based RF Technology. The advantages of the main products are mainly embodied in the following five aspects :

Advantage 1  Full Integrated RF front-end Chip with High Power and Low Delay

KCT8101L is a fully integrated RF front-end chip,  Internal integration of the necessary power amplifier ( PA ), low noise amplifier ( LNA ), high power RF switch ( T/R  Switch ), 50ohm matching circuit and internal logic control circuit. The frequency coverage of KCT8101L is 780MHz ~ 960MHz can be widely used in NB-IoT/LoRa and other requirements. In addition, the internal integrated logic circuit can implement PA/LNA ns level stability response speed, thus simplifying the external control circuit. KCT8101L can provide the power gain of 27dB and the maximum output power of 27dBm in the whole frequency domain, which can greatly improve the coverage of the system.
