In the 5G war, the largest 5G baseband chip's batch of Huawei, ZTE, ZTE, ZTE occupies the frontier position, overseas companies only high-pass, Samsung, Apple (acquisition Intel 5G baseband business) is doing a 5G baseband chip.
However, in terms of radio frequency chips, 90% of the market have been held by foreign manufacturers, and our domestic manufacturers are only worried about technology and scale. There is no other way to open up the second battlefield of RF chips, this problem is worthy of depth research.
What is a radio frequency chip
Due to the popularity of the 5G network, it is often possible to see the report on the baseband chip on the media. The terminal wants to use the 5G network, more than a baseband chip, but also has the support of RF chips and antennas.
For an alteration, the baseband chip is equivalent to the light cat, responsible for signal processing and protocol processing. The RF chip takes the function of transmitting signals and reception signals.
Simply, the function of the RF chip is to convert the binary signal into a certain frequency of radio signals and send it through the antenna. It can be said that there is no radio frequency chip, the terminal cannot be transformed, and there is no way to go online.
5G RF chip technology really urgently 35 billion knife market needs to open the second battlefield
5G RF is 3 times the 4G RF market
The 5G era, the new wave change machine is coming, and the RF chip market will also usher in explosive. The cost of the 4G RF chip is around 12 US dollars, while the cost of the 5G RF chip is about $ 34, almost three times the 4G RF chip. It is expected that in 2023, the RF chip market will reach $ 35 billion.
4 giants account for more than 8%
At present, the RF chip market is mainly occupied by Skyworks, Qorvo, Bo Tong, and Japan Murata, and the four markets account for 85%. In this case, it can be said that the RF chip market is completely held by overseas companies, and domestic manufacturers have no sayings.
Radio three components have no domestic
The internal radio frequency chip is composed of a PA, a switch chip, and a filter. PA is the core that affects the distance and signal quality, and a 5G mobile phone takes more than 15 PA chips. The PA RF chip is more difficult to manufacture, and domestic manufacturers are absent from the field, still Skyworks, Qorvo and Boyong hold.
Mei Da Monopoly Filter
In terms of filter, a 5G mobile phone takes more than 40 filters. This field, the US and Japan manufacturers are monopoly. Foreign RF chip giants are complete, product maturation. This means that in 5G this new wave change machine, our company can only look at others to earn money, do anxious.
Time space is less and less
There is less space left to the RF chip on the terminal, which means that more electronic components should be accommodated on each radio frequency chip. Although we have made great progress in various fields, the technology accumulation in the field of RF chips is weak.
Perhaps open the second battlefield
Since there is no chance on the high-end radio frequency chip, it may open up the second battlefield to be another way out.
Why is the high-end radio frequency chip? Because you need to support more frequency bands, it is best to do support for all-band, which is our common Netcom.
Going to the country, you can enjoy the local network without change your phone. In this way, more components should be deployed on the RF chip to meet demand.
Some mobile phone manufacturers are facing India, Southeast Asia, Africa, South America and other markets, these areas do not need to support so many frequency bands, only need to support local frequency bands.
In this way, the requirements for the radio frequency chip are greatly reduced. Domestic manufacturers can accumulate technical experience through this road, gradually advance to the high end of RF technology and alternative direction.
Conclude
The people who have the 5G era must be awake, our 5G is missing, the second battlefield is summoned.
