In mobile terminals such as smartphones and wearable devices, RF filters are the cornerstone of communication quality and user experience. With the evolution of 5G/6G technologies, the number of communication frequency bands continues to increase—each new band requires a corresponding filter, driving extreme demands for miniaturization, high performance, and high integration. Filters must achieve precise frequency selection and interference suppression within limited space, ensuring clear voice calls, high?speed data transmission, and accurate navigation.
Shoulder's SAW filter product portfolio covers filters, duplexers, and multi?filter devices from low to medium?high frequency bands, supported by mainstream technology platforms including SAW, TC?SAW, and TF?SAW, covering critical frequency bands from 600MHz to 2800 MHz. Packaging offerings include SMD, CSP, WLP, and Bare?Die, among others, capable of meeting the dual challenges of space and performance in smartphones, tablets, smartwatches, and other devices. Notably, WLP and Bare?Dieproducts have achieved substantial shipments in RF front?end modules, demonstrating the company's synergistic development capability in the high?end filter sector.
