About KNOWLES

Knowles is a market leader and global provider of high-performance capacitors and radio frequency ("RF") filtering products, advanced micro-acoustic microphones, balanced armature speakers, and audio solutions, serving the medtech, aerospace/defense, industrial, electrification, and consumer electronics markets. As a specialty components manufacturer, we at Knowles choose to take on the complex challenges that come with high-reliability, high-temperature, high-performance, and high-frequency solutions for industries and applications where failure is not an option. To tackle these challenges, at our US-based manufacturing facilities we adhere to the highest military-grade quality and reliability standards so that our components are qualified for use in even the most sophisticated and secure military and aerospace applications. At Knowles we have more than 40 years' experience developing high-performance microwave components for military applications. Therefore, as more applications take advantage of mmWave frequencies, it is a natural transition for us to expand our expertise to supply high-performance components that enable communications at these frequencies as well. Knowles has a complete range of RF and microwave filtering solutions that support applications from VHF to Ka band. Our filters offer stable performance over a wide temperature range, -55⁰C to 125⁰C, and are rigorously tested to ensure the highest standards. Additionally, we can now deliver ceramic, lumped element, and a wider range of cavity filters for lower frequency and/or high power applications. No matter the complexity, we have a solution! Stop by our booth and ask us about our 2-18GHz Highpass and Bandpass Filters that we are now sampling, or our catalog parts, build to print offering, or our custom design capabilities.
