No, 5G RF chips and filters are not the same thing. 5G RF chips are mainly used in wireless communication equipment, which is responsible for receiving and sending wireless signals, and processing related functions such as modulation and demodulation, encoding and decoding. The filter is an electronic device used to filter the specific frequency components of the wireless signal, which can remove noise and interference to ensure the quality of the signal. Although RF chips and filters are often used together in 5G devices, they are two different components with different tasks to guarantee high-speed, stable wireless communication.

The filter is one of the core components of the 5G RF front-end, and it is not difficult to see this from the value chain, according to statistics, in the current global RF device market of about $15 billion, the filter accounts for $8.1 billion of the volume.

At present, the high-end filter can be mainly divided into surface acoustic wave (SAW) and body wave (BAW) two technical routes, SAW filter market is mainly ruled by Japan Murata, BAW filter market is monopolized by Broadcom, Skyworks, Qorvo, Qualcomm and other American companies, Chinese companies accounted for very little.
