The future world is a wireless connection to all worlds. According to Gartner predicts, in 2015, only 2.9 billion tibne equipment in the global consumer industry, the industrial application field is only 736 million tibid networking equipment. By 2020, networked equipment will reach 25 billion, achieving the size of 3 connected equipment for each person in the world. The annual output value of the RF device will also be multiplied in the large trend of the outbreak growth of the wireless network terminal device.
Radio front end soldiers must fight: filter
The RF device is the basic components of the wireless communication device. With the popularity of the CMOS RF integrated circuit, more and more modules are transferred from the discrete device to the integrated circuit. However, there are some devices that are currently unable to manufacture the highest integration CMOS process, but must use special processes to ensure performance. These wireless devices that cannot be integrated into RFIC are often referred to as RF front end modules (RF Frontend Module).
A typical radio system architecture containing FEM and RFIC / MODEM
The RF front end module consists of power amplifiers, filters, duplexers, radio frequency switches, low noise amplifiers, receiver / transmitters, and the like. As mobile device functions are more and more powerful, supported network bands increasingly, radio front end The module became an indispensable part of the mobile device. In 2015, the global mobile terminal RF device market has approximately $ 11 billion. According to the prediction of Qualcomm semiconductor, the radio front end module of the mobile terminal has more than 13% of the compound growth in 2015-2020, and the market size will exceed $ 18 billion in the 2020, and the filter is the fastest growing radio front end module. In the direction, the filter market will increase from $ 5 billion in 2015 to $ 13 billion in 2020. The forecasting and high pass of Mobile Experts is basically consistent. In 2016, the growth rate of the RF front-end module has reached 17% in the case of smartphone growth (9%), and the fastest and most critical development of development is also the filter module.

Radio front end various sub-directional market space predictions ($ $ 200 billion)
In the future, the RF filter market will also usher in more growth. Because with 4G maturation and 5G, the number of cells supported by mobile phones is rising. In the 2012 World 3G Standard Association 3GPP, the cellular communication system needs to support the frequency band to 41. According to RF device giants Skyworks, by 2020, the number of frequency bands supported by 5G applications will be doubled, and more than 50 communication bands, the global 2G / 3G / 4G / 5G network total support will reach more than 91. For a frequency band, there is generally at least two filters, so the direct result of the number of mobile phone bands rises is the number of radio frequency filters used in the phone.
Electronic component leadership manufacturer TDK has top technology in the field of RF filter, currently over 25 million filters per day, and the number is still growing, involving customers cover all major mobile phone OEM vendors, including the first smartphone industry. According to relevant institutional analysis, IPHONE 7 TDK-EPC (Epskos (China) Investment Co., Ltd. • TDK Group Member, 2017 Munich Shanghai Electronics Show Booth: E5.5306) Supply 2 filter banks and a filter. At the same time, TDK-EPC's three-line EMC filter, high performance capacitive electrical resistance devices, etc., are also used by many internationally renowned manufacturers.

At the same time, as mobile communications tend to high-speed, large-capacity data transmission, smartphones such as mobile devices such as mobile devices require multi-port support and higher radio frequency performance. At this point, it is a particularly important factor in reducing the insertion loss because it reduces the RF transmission power loss to support mobile devices with longer battery life. The new generation of TARFSOI, which is developed by Semiconductor and Storage Products (2017 Munich Shanghai Electronics Show: E4.4300) (SOI)) Process - "TARF8" optimized for RF switch applications, The industry is ultra-low insertion loss (0.32 dB / 2.7GHz). The transmission RF switch ICSP12T manufactured by the mobile application manufactured by the new process is equipped with an integrated MIPI-RFFE controller for 3GPP GSM, UMTS, W-CDMA, LTE, and LTE-Advanced standards.
Meet the next generation of mobile network needs, not only the radio frequency device is simple!
In addition to the evolution of the RF device itself, the RF system in the entire communication system also changes accordingly as the evolution of the new generation of mobile networks. Throughout the development of the mobile phone communication protocol, the channel bandwidth is constantly increasing, the 200kHz, 3G era of 2G era, 100MHz of the 3G era, to the 5G era or even close to 1GHz, continuously increased bandwidth to promote the same macro base station and small The base station topow has a powerful heterogeneous combination of smaller honeycomb base stations.
The cellular mobile network has evolved for many years, according to GSMA's market research statistics, in 2020, the number of devices used in cellular networking technology in the world will reach more than 100 billion units. For the growing demand for bandwidth and cellular wireless sensitivity, the transmission of RF signals to the remote radio head ends in the honeycomb antenna will be increasingly demanding. At the same time, the limitations of the connector size and weight are also more stringent.
The connector has been well known to many people now, and the number of radio connector is increasing in the market, mainly used in RF coaxial systems. Interconnect Product Giants Molex (2017 Munich Shanghai Electronics Show, Booth No .: E6.6400) Recently launched 4.3-10 RF connectors and cable components to meet the needs of next-generation mobile networks. High-performance signal transmission effects under low passive intermodulation (PIM), 100% data traceability, lower torque than the current interface. The connector included in the solution is 30% lower than DIN 7/16, the weight is 60%, and the cable assembly is integrated with a wind-resistant rain cover. It is applying for patents, ideal for outdoor honeycomb points, is the future The election of the cellular communication micro base station is connected.
