What's New At Knowles

Over the last five years, Knowles Precision Devices has made a number of moves to grow in size, reach and product development. In 2021, we acquired Integrated Microwave Corporation (IMC), a leader in the design and manufacture of custom precision RF microwave filters and multiplexers for the aerospace, defense, and communications industries.

The acquisition of IMC helps us expand our offerings to serve applications operating in the lower portion of the frequency range from VHF to L band. While we have always offered RF and microwave products that excel at filtering in applications operating from S to Ka band, now we have a complete range of RF and microwave filtering solutions that support applications from VHF to Ka band. We can now deliver ceramic, lumped element, and a wider range of cavity filters for lower frequency and/or higher power applications.
