BSC Filters

Company Profile:

BSC Filters, founded in 1989 and headquartered in York, UK, became part of the Dover Corporation’s Microwave Products Group (MPG) after its acquisition in 2010. Renowned as a technical leader in passive microwave components, BSC Filters specializes in the design and manufacturing of ​coaxial and waveguide filters, ​duplexers, and related subsystems, offering full-spectrum services from conceptual design to mass production. The company serves diverse markets with cutting-edge solutions.

BSC Filters is dedicated to delivering high-performance ​filters and ​duplexers operating up to ​94GHz, with core expertise in waveguide, digitally controlled integrated, cavity, suspended substrate stripline, and microstrip technologies. Its product portfolio also includes ​couplers, ​equalizers, ​switchable filters, and ​waveguide assemblies.
