Paul Leclaire, PhD, Patent Analyst at KnowMade, said: 'In this dynamic context, RF SAW filters have become the best solution to achieve filter operation in the band below 6 GHz. "In fact, SAW filters are inexpensive to produce but Achieving a high level of consolidation and performance So far, no other technology solutions provide a better trade-off.
Acoustic wave filter patent application activity was very high from 2000 to 2006, gradually slowing down and reaching plateau stabilization period since 2010. The market was mainly dominated by traditional vendors with strong international status, greatly reducing the number of new entrants into the industry Penetration rate from 2017 to 2022 is projected to grow at a CAGR of 8%: Sonic technology has become the best way to deliver high performance, small size and low cost filters in analog RF communications.
The same trend has emerged in the field of intellectual property, dominated by a handful of major companies such as Broadcom, Skyworks, Taiyo Yuden and Murata, which have solidified their position since the rapid development of 2000-2006. Mergers and acquisitions led to a stronger vendor portfolio. Broadcom's acquisition of Avago Technologies is a good example of this. In addition, with the formation of the 5G communication protocol, various vendors are now developing filters to meet the upcoming 6GHz The following applications and the needs of the next 5G mass market.
SAW is the main technology for mobile communications. Patent activity began in the early 90s and the layout of the patented vendors was fully established. Intellectual property activities were promoted by Murata Manufacturing thanks to its already licensed and pending patents .
BAW's patent activity showed more momentum than the SAW segment, and Broadcom's strong product portfolio was consolidated as a result of the acquisition of Avago Technologies BAW's intellectual property market is not as well developed as SAW, and KnowMade's Analyst The market is expected to reshape in the next five years due to competition between the major challengers of intellectual property, for example, both Qualcomm and Qorvo have demonstrated compelling patent campaigns related to the 4G to 5G transition This strategy may reshuffle the BAW intellectual property market and intensify competition.
