With the deep deployment of 5G networks and the evolution toward 6G, small cells are seeing surging demand due to their flexible deployment and complementary coverage capabilities. This has created a clear driving force for filters with smaller size, lower cost, and higher performance. SAW filters, with their advantages of compact size, low cost, and excellent consistency, are highly compatible with the requirements of small cells and have been widely used in telecommunications infrastructure such as macro base stations, micro base stations, small cells,and repeaters.

Shoulder's base station filter products are broadly deployed in macro cells, micro cells, small cells, repeaters, and other telecom infrastructure,covering a frequency range from 400 MHz to 6000 MHz to fully meet communication requirements from 4G to 5G/6G. Leveraging the stable delivery capability and technological strengths of its IDM model, the company provides highly reliable, high‑power‑tolerant filtering solutions for base station equipment, satisfying the dual demands of 5G network construction for core component performance and supply stability.
