EPCOS SAW Filters and Resonators

View Products List

EPCOS SAW (surface acoustic wave) Filters and Resonators are AEC-Q200 qualified to satisfy harsh condition requirements, as well as shock and vibration. Hermetically sealed in ceramic packages that can withstand temperatures from -40°C to +125°C, the EPCOS SAW Filters and Resonators are ideal for your newest designs in advanced metering infrastructure (AMI) systems, radio-based systems, access controls, fire and intrusion alarm systems, automotive, pressure monitoring, and RKE (remote keyless entry).

- Machine to Machine (M2M) SAW Filters -

M2M is the abbreviated form of "Machine-to-Machine". The term is used to refer to machine-to-machine communication, i.e., automated data exchange between machines.

M2M technology will increasingly underpin key areas of the economy, for example, the smart (green) grid, networked homes, healthcare in the home and transportation (usage-based auto insurance and the
emergency eCall system for cars). Numerous opportunities are opening up for vendors, solution providers, systems integrators, and MNOs.

M2M concepts are ideal for forming the basis of solutions for a large number of tasks, particularly in vertical markets.
