需要新的宽频解决方案

自 1990 年代以来，声学滤波器产业已分为两种主要技术：低频段声表面波 (SAW) 滤波器和高频段声表面波 (BAW) 滤波器。 该市场和公司都很成熟，其产品、技术和专有技术受到庞大且强大的智慧财产权 (IP) 组合的保护。 Murata Manufacturing 和 Skyworks 在 SAW 专利方面领先，而 Broadcom 在 BAW 专利方面领先。 随着行动电话服务和网路的扩展，频段逐渐变得更宽、更高。 例如，在5G应用中，除了sub-6GHz频段（例如3.3-3.8GHz（B78）、3.3-4.2GHz（B77）、4.4-5.0GHz（B79））之外，毫米波频段（例如24.25-29.5GHz ) （B257、B258、B261）、37-40GHz (B260)）。 达到更高的频率是挑战的一部分；另一个挑战是提供不仅在更高频率下工作，而且还提供更宽的绝对和相对频宽的射频滤波器。

目前，SAW 和 BAW 装置符合 3GHz 以下频段的要求。 然而，当涉及到3-5GHz频段时，就出现了许多问题。 SAW 装置需要越来越窄的电极宽度，从而导致更高的损耗、较差的功率处理能力以及更高的光刻成本。 BAW 装置同样具有相对较低的压电耦合，并且缺乏支援急需的高频宽的能力。 因此，解决损耗、功耗和散热问题以及 3 GHz 以上频宽需求的新解决方案变得很有吸引力。

为了克服这些限制，公司正在寻找新技术。 新的解决方案包括开发具有 ScAlN 或 Sc 掺杂 AlN 压电薄膜的 BAW，以增强电声耦合性能。 同时，新型复合基板的开发为SAW领域开启了新的大门。 最后，横向激励体声波（LBAW）技术也进入了竞争。

许多公司将这种演变视为进入这个利润丰厚的市场的机会，并明确希望成为 5G 下一代射频滤波器的下一个供应商。 这样，不仅是新进者，现有公司也都进入了激烈的竞争，而智慧财产权可以成为支持其策略的关键工具。 此外，中美技术竞争带动了中国国家供应链的发展。 这些因素共同构成了一个高度动态和竞争的产业。

在此背景下，射频声波滤波器专利态势报告旨在了解当前的智慧财产权活动以及它们如何支持公司的市场策略。 透过分析 25,000 多项专利，可以为公司如何利用其智慧财产权来确保自己的地位或获得新的市场份额提供独特的见解。

了解主要趋势、主要公司的智慧财产权地位以及智慧财产权策略

本报告手动提取了超过 11,000 个与 SAW 滤波器、BAW 滤波器以及多路復用器和 RF 前端模组相关的专利族（发明），以概述当前全球 IP 格局。趋势和概述事态发展。 透过专利分析，我们解释每家公司在供应链上的地位，揭示加强其智慧财产权组合的策略，强调其限制其他公司专利活动和营运自由的能力，并识别有前途的新公司，识别和预测未来的知识产权领导者。 此外，该报告还可以让您了解每家公司在有前途的技术方面的智慧财产权地位。 它确定了参与开发新技术的关键公司，并描述了应对这些挑战的主要解决方案。

本报告强调，SAW 与 BAW 之间的智慧财产权格局存在重大差异。 一方面，SAW滤波器的发展已经达到高度成熟，IP公司开始转向模组化设计和滤波器架构。 特定产业的创新者在智慧财产权领域占据主导地位，很难挑战他们。 另一方面，BAW IP 格局的特征是竞争激烈。 最近博通和太阳诱电的专利活动下降，加上 AlScN 压电层的兴起，正在创造许多中国和老牌 SAW 公司不容错过的新机会。

中国IP企业的定位与策略是什么？

这份报告让您了解中国主要企业的智慧财产权现况。

本报告首次确定了最着名的中国专利持有者，并分析了他们如何开发智慧财产权以建立国内供应链。 此外，透过智慧财产权分析，我们发现正在透过向海外拓展专利来实施国际智慧财产权策略的中国企业。 最后，我们全面调查了最着名的中国公司的专利活动，并分析了他们近年来的技术进步。

IP 如何支援新滤波器技术的开发？

5G 需求催生了多项新技术的发展。 最值得注意的是过滤器中使用的基材和材料。 复合压电基板和AlScN已成为满足要求的两种最有前途的技术。 为了确保未来 10 年的技术安全，必须申请与这些技术相关的专利。 KnowMade 首次分析了这个特定智慧财产权领域的格局，并调查了哪些公司拥有最强大的智慧财产权组合。

The need of new solutions for high bands

Since the 1990's, the acoustic filter industry has been divided into two main technologies: surface acoustic wave (SAW) filters for the lower bands and bulk acoustic wave (BAW) filters for the higher bands. This market and the players were well-established, and their products, technologies, and know-how were protected by large and strong intellectual property (IP) portfolios. Murata and Skyworks were leading the SAW patent landscape, while Broadcom was leading the BAW one. The expansion of cell phone services and networks drove the need for progressively wider and higher frequency bands. 5G applications, for instance, require frequencies in the sub-6GHz range (e.g., 3.3-3.8 GHz (B78), 3.3-4.2 GHz (B77), 4.4-5.0 GHz (B79)) as well as mm-wave bands (e.g., 24.25-29.5 GHz (B257, B258, B261), 37-40 GHz (B260)). While reaching higher frequencies is one part of the challenge, the other part is to provide RF filters that not only work at higher frequencies, but also offer wider absolute and relative bandwidths.

Currently, SAW and BAW devices fulfill the requirements for bands below 3GHz. However, when it comes to the 3-5 GHz range, numerous issues arise. SAW devices require increasingly narrower electrodes, which result in higher losses, reduced power handling, and more expensive lithography. BAW devices likewise have relatively small piezoelectric coupling and lack the capacity to support the wider bandwidths required. Therefore, new solutions that address losses, power, thermal issues, and bandwidth needs above 3 GHz will be attractive.

To overcome these limitations, players are looking for new technologies. New solutions include the development of BAW with a ScAlN or Sc-doped AlN piezoelectric film in order to enhance the electroacoustic coupling characteristic. On the other hand, the development of new composite substrates has opened new doors for the SAW segment. Last, laterally excited BAW (LBAW) technology has also entered the race.

Many players have seen this evolution as a good opportunity to enter this lucrative market and explicitly desire to be the upcoming provider of the next generation of RF filters for 5G. Newcomers as well as established players have thus entered a fierce race in which IP can be a major tool to support their strategy. Furthermore, the US vs. China technology battle has led to the development of a national supply chain in China. All these elements are adding up to result in a very dynamic and competitive industry.

In this context, the RF Acoustic Wave Filters Patent Landscape report aims to understand the current IP activities and how they can support the market strategies of players. The analysis of more than 25,000 patents offers a unique view of how players can leverage their IP to secure their position or conquer new market shares.

Understanding the main trends, the key players' IP position and IP strategy

In this report, we have manually selected more than 11,000 patent families (inventions) related to SAW filters, BAW filters, and multiplexers and RF front-end modules using them, and provide a general overview of today's IP landscape global trends and dynamics. Through patent analysis, we describe the position of players along the supply chain, unveil their strategies to strengthen their IP portfolio, highlight their capability to limit other firms' patenting activity and freedom-to-operate, identify promising new players, and forecast what would be the future IP leaders. Furthermore, this report provides an understanding of players' IP position on promising technologies. The main players involved in the development of new technologies are identified, and the main solutions to address these challenges are described.

The analysis highlights a significant difference between the SAW and BAW IP landscape. On one hand, the development of SAW filters has reached a high level of maturity, and IP players have started to look at module design and filters architecture. Vertical innovators are controlling the IP landscape and will be difficult to challenge. On the other hand, the BAW IP landscape is characterized by intense competition. The recent decline in patent activity from Broadcom and Taiyo Yuden, paired with the rise of the AlScN piezoelectric layer, has created new opportunities that numerous Chinese players and established SAW players are not going to miss!

What is the position and strategy of Chinese IP players?

The report provides an understanding of the current IP positions of major Chinese players.

We have identified the most noticeable Chinese patent owners and provide a first view of how they are developing their IP in order to establish a national supply chain. Additionally, the IP analysis allows us to pinpoint Chinese players who are implementing a global IP strategy by extending their patents abroad. Lastly, the report offers a comprehensive overview of the patent activity of the most noticeable Chinese players, providing insight into their recent technological advancements.

How can IP support the development of new filter technologies?

The 5G requirements led to the development of several new technologies. The most noticeable being related to the substrate and materials used in the filters. Composite piezoelectric substrates and AlScN have become two of the most promising technologies to fulfill the requirements. Filing patents related to these technologies seems necessary to secure the technology for the next 10 years. KnowMade provides a first status of this specific IP segment to understand which players have the strongest IP portfolio that can be used to hamper the freedom to operate of the competition in the coming years.
