1. filter market size
According to data from the Champ Consulting Group,2020To2022年,全球滤波器市场规模受到新冠疫情的影响,出现了一定程度的下降,2022year63.5Billion US dollars, lower than the same period last year.4.14%. This is mainly due to the impact of global smartphone shipments and chip shortages,2020Annual decline5.8%,2021Annual decline3.2%。2023年第一季度,随着疫苗接种和经济复苏的推进,全球智能手机出货量为3.6Billion units, year-on-year growth.4.1%. Expected2023年全年全球滤波器市场规模将恢复增长,达到75.6Billions of dollars.
Champ Consulting believes that with5G时代的到来,高速、低延迟和广泛覆盖的网络时代到来,5GApplications have also been extended to mobile communications, cloud computing, autonomous driving,VR/ARAnd many other vertical industry application scenarios, with the emergence of various types of downstream end products, as a5G通信技术的核心硬件,射频前端芯片的市场需求持续提升。滤波器是射频前端芯片中价值量最高的细分领域,且增长最快。从射频前端价值分布占比来看,滤波器占比达53%。
市场空间潜力巨大。5G时代的来临使得滤波器迎来了广阔的发展前景,其广泛应用于智能手机、无线路由器、卫星导航系统、平板电脑、智能手表及其他物联网等市场。预计2023年全年,全球滤波器市场规模增长至225亿美元,增长率为19%,
二、滤波器分类及应用
滤波器主要可分为金属腔体滤波器、介质滤波器、声学滤波器;其中金属腔体滤波器、介质滤波器主要应用于宏基站、小基站;声学滤波器可分为声表面波滤波器(SAW Filter) and bulk acoustic wave filter (BAW Filter), mainly used in mobile phones, small base stations, Internet of Things and other fields.
SAW filter volume is smaller than the traditional cavity and ceramic filter, the production process is relatively simple, low cost, can meet1G~3G移动通信等标准频段以及部分4GThe frequency band is the mainstream choice in the mobile phone filter market, and its disadvantages are insufficient high-frequency performance and poor thermal stability.TC-SAWThe filter is boostedSAWThermal stability of the filter;BAWThe filter can handle frequencies up6GHz,在频率大于1.9GHzof4Gand5GThe frequency band has application advantages, but the disadvantage is that the production process is difficult and the cost is high.
With5GWith the increase of frequency bands in the era, the market demand for high-performance filters will increase, and the useBAWThe technology can design a narrow-band filter with a very steep filter skirt, high suppression performance and small temperature drift to solve the problem of interference suppression between adjacent frequency bands.
3. filter competitive landscape
全球滤波器市场高度集中,主要被美国、日本企业垄断,SAWIn the filter market pattern, Murata ranks first, with a market share of about50%,TDKProportion22%, solar induced electricity accounted15%, the top three manufacturers together accounted for up87%。
BAW filters are more concentrated and are used by Broadcom andQorvo两家厂商垄断,市场占有率分别为56%、38%,此外,太阳诱电和TDK分别占比4%and2%。
在中国市场,滤波器国产化整体进程仍处于初步阶段,国内行业整体技术水平与国外领先厂商相比仍存在较大差距,国内声表面波滤波器产业的发展尚无法满足国内需求,大量手机滤波器仍依赖进口。国内供给缺口大,市场空间广阔,具备尖端声波滤波设计专利以及工艺设备的滤波器厂商或将成为破局的关键。
四、滤波器发展趋势及建议
据尚普咨询集团数据显示,未来滤波器行业的发展趋势主要有以下几个方面:
5G驱动滤波器量价齐升,射频模组化大势所趋。手机通信从2G发展到5G,单机滤波器价值量不断提升。单机滤波器价值量的提升一方面来自滤波器用量的增加,早期2G手机的频段数量仅为4个,而5G手机的频段数量大幅提高至50多个,对应的单机滤波器数量也从2个提升至70多个,同时MIMOwithCA技术的深度应用进一步促进了5G手机滤波器用量的提升;另一方面,5G时代下滤波器朝着小型化、集成化、高频化的趋势发展,对射频滤波器在设计、制造、封装等方面提出更高要求,从而推升产品单价。为了降低射频前端的复杂度和成本,实现更高的性能和效率,射频模组化是必然趋势。射频模组是将多个射频前端芯片(如功率放大器、滤波器、开关等)集成在一个基板上,并进行封装和测试,形成一个功能完整的模块。射频模组化可以提高系统可靠性、缩短产品开发周期、降低生产成本、节省空间等优点。
5G基站建设中,陶瓷滤波器将会逐步取代金属腔体滤波器成为主流。3G/4G时代,基站滤波器市场中金属腔体滤波器是绝对的主流,进入5G时代后,基站的高度集成化和小型化趋势对滤波器的体积、重量、散热性等特性有了更高的要求,而金属腔体滤波器体积大、重量大、散热性差,于是行业主要使用小型金属腔体滤波器和陶瓷介质滤波器2种方案来解决该问题。小型金属腔体滤波器虽然减小了滤波器的体积和重量,但主要应用于2.6GHz以下的低频段,而陶瓷介质滤波器具有体积小、重量轻、高Q值、插入损耗小、可承受功率高等优点,未来在5G基站滤波器市场上渗透率将不断提高,成为主流选择。
国产化进程加速,国内厂商加大技术创新和投入。在全球市场上,美国和日本企业垄断了声表面波和体声波滤波器市场,拥有核心技术和专利。在中国市场上,国内厂商在声表面波和体声波滤波器领域的技术水平和市场份额仍有较大的差距,大量滤波器仍依赖进口。为了打破国外厂商的技术壁垒和市场垄断,国内厂商加大了技术创新和投入,积极推进滤波器国产化进程。例如,紫光展锐推出了基于IPD工艺的高频滤波器,实现了对博通和Qorvo的突破;中电科微电子推出了基于MEMS工艺的可调谐滤波器,实现了对村田和太阳诱电的突破;中芯国际推出了基于SOI工艺的集成滤波器,实现了对TDK和村田的突破等。
尚普咨询建议,滤波器行业的发展需要各方面的共同努力,包括:
政府部门应加大政策扶持和资金投入,鼓励国内厂商进行技术创新和产业升级,提高滤波器国产化水平和自主可控能力。
行业协会和标准机构应加强行业规范和标准制定,促进行业健康有序发展,提高行业竞争力和影响力。
企业应加强技术研发和人才培养,加快产品开发和上市速度,提高产品质量和性能,降低产品成本和功耗,拓展产品应用领域和市场份额。
学术界和研究机构应加强与企业的合作交流,加快技术成果的转化应用,提高技术创新能力和水平。
