As communication technologies accelerate their evolution toward integrated terrestrial‑satellite‑aerial networks, emerging applications such as LEO (Low‑Earth-Orbit) satellite communications, industrial IoT, unmanned aerialvehicles (UAVs/drones), and NB‑IoT are rapidly gaining traction. The sescenarios present new challenges for RF front‑end chips, including higher frequencies, miniaturization, and enhanced reliability. SAW filters, with their superior frequency selectivity and environmental adapt ability, have become indispensable fundamental components in these emerging fields.

In other application areas, Shoulder's filter products are also widely used in CPE (Customer Premises Equipment), industrial routers, drones, NB‑IoT devices, and other equipment, covering a frequency range from 300 MHz to 3500 MHz. Leveraging its IDM model, the company canrapidly respond to diverse requirements for filter performance, power consumption, and cost across different scenarios, providing reliable RF front‑end support for the large‑scale development of emerging.
