China filters usher in an important breakthrough

5G-driven RF filters are developing rapidly

As an important component of the radio frequency front end, radio frequency filters are mainly used in the base station market and mobile phone market of wireless communication terminals, and play an important role. Take a mobile phone as an example. If the mobile phone does not have a filter, it means that the communication device has lost its anti-interference ability and cannot guarantee smooth communication. In short, whether the signal of a mobile phone is good or not depends on the filter. A smartphone without a filter can be said to be a brick.

With the acceleration of 5G commercialization, 5G mobile phone shipments will usher in rapid growth. As the number of radio frequency filters required for a single 5G smartphone is higher than that of non-5G mobile phones, the rising penetration rate of the 5G mobile phone market will accelerate the growth of the demand for radio frequency filters. In addition, the large-scale construction of 5G base stations also increases the demand for filters.

According to Resonant statistics, the global RF filter market has grown from USD 5 billion to USD 15 billion in 2016-2020, with an average compound growth rate of 31.6%. It is estimated that the market size is expected to exceed USD 28 billion by 2025.

Chinese filter companies usher in opportunities

At present, my country's domestic filter market is severely under-supply, and national output is far from demand. In addition to the continuous escalation of Sino-US trade friction, domestic replacement of filters is imperative. With the advancement of 5G technology becoming more and more mature, the conditions for the development of domestic filters have gradually begun to mature, and domestic manufacturers are also accelerating their breakthroughs, focusing on achieving localization and high-end filters. At present, the domestic filter market can be described as a cohesion.

The main business direction is Anhui Yunta Electronics, which develops and sells RF front-end chips and module products represented by RF filters. The current miniaturized millimeter wave filter products can not only be applied to various 5G terminals and base stations, It can also provide a cost-effective filtering solution for the next-generation 6G low-orbit broadband satellite Internet.

It is worth mentioning that not long ago, Yunta Technology and the School of Microelectronics of the University of Science and Technology of China released its self-developed 5G millimeter wave filter, which uses a unique ultra-high-performance integrated passive device (SPD) technology, which also marks Domestic millimeter wave technology has taken a key step in the commercialization process.

Recently, the industry leader Jingxun Juzhen officially released its self-developed B41 full-band FBAR filter and B40 filter in Zhuhai, which not only supports high power, but also reduces the package size, and has the industry’s thinnest WLP package. The excellent performance of large bandwidth, high out-of-band suppression and low insertion loss breaks the monopoly of foreign countries such as the United States and Japan, laying a good opportunity for the development of domestic RF chip manufacturers.

Filters have always been a typical "short board" dilemma in my country, and the high-end market is even blank. However, it is fortunate that, driven by 5G, China has ushered in the dawn of the RF filter field. Although it started late, it is not impossible to break the foreign monopoly. Only by working together to continuously explore high-end areas can we have the opportunity to surpass international giants.
