The opportunity of the radio frequency industry in the 5G Era
2018-07-12 10:15:06

RF devices are the heart of wireless connectivity, and are essential RF devices where wireless connectivity is required. Driven by IoT applications, the number of wireless connections in the world will multiply in the future. Qualcomm estimates that by 2020, there will be more than 25 billion terminals connected to the world via wireless connectivity.

 

The demand for wireless connectivity is not limited, and the RF device industry has a constant opportunity. There are more and more wireless connection protocols for mobile phones, and the direct drive RF device industry continues to grow. From the early 2G single communication system to the current 2G, 3G, 4G, wifi, Bluetooth, nfc, FM, the mobile phone needs to support more than 7 wireless communication systems, and the RF device is worth several times the system of a decade ago. 

 

The 5G evolution is a gradual process, and innovative RF device technology is expected to be applied at 4.5/4.9G. During the evolution of 2G to 3G, wireless communication has experienced three stages: UMTS, HSPA, and HSPA+; the evolution of 3G to 4G has gone through three stages: class 1-2, class 3-4, and class 5. We believe that the evolution to 5G is also a gradual process that will experience intermediate forms such as 4.5G/4.9G. In these intermediate forms (around 2018), there will be some RF technologies for commercial applications. RF devices have a vital application in the consumer electronics and military industries, and the emphasis on industrial capital and national funds will increase. With the help of the capital of all parties, the domestic RF device industry will usher in a new round of industry development opportunities. 

 

PA chip field: PA chip industry ushered in interface standardization and GaAs wafer foundry transfer to the domestic two dividends, domestic PA manufacturers' product development and production process is smoother, it is expected that the domestic replacement rate will be greatly improved in the 5G era. At present, a number of outstanding PA manufacturers such as Han Tianxia, Zhongpuwei and RDA have emerged in China. 

 

Filter field:

By 2020, the number of frequency bands has increased by more than 50. In theory, a new frequency band needs to be equipped with two filters. The number of frequency bands directly increases the number of directly driven filters.

 

Antenna field: The application of MIMO multi-antenna technology has doubled the number of antennas for a single mobile phone and base station. The biggest change in 5G is the introduction of high frequency bands. The design of the antenna will be changed from the existing single antenna to the array antenna. The new magnetic material and LTCC integration technology will be the core technology of the 5G antenna. Domestic manufacturers have taken the lead in the international market in 4G antennas, and the products have entered the high-end mobile phone brands such as Apple and Samsung. In the field of centimeter wave and millimeter wave communication, domestic research institutes have accumulated rich technical experience, and radar and satellite communication technologies are in a leading position in the world. We are optimistic about the transformation logic of military centimeter wave/millimeter wave technology to the field of consumer electronics driven by the 5G wave.span>
