Switch Solutions for Systems with Low PIM Requirements

Dow-Key Microwave, the Leader in RF and Microwave Switch Manufacturing, Has Released A New White Paper on Switch Solutions

Ventura, CA, August 18, 2011

Low PIM SwitchesDow-Key Microwave Corporation, the leading manufacturer of electromechanical switches in RF and microwave applications, is proud to announce the release of their brand new white paper, “Switch Solutions for Systems with Low PIM Requirements.”
Dow-Key Microwave has invested in R&D for new RF switch products designed specifically to reduce intermodulation (IM) in coaxial switches. The introduced family of special RF switches meets the very stringent and low intermodulation requirement of-160 dBc PIM level imposed by today’s test and communication industries.


Adolf Cheung, VP of Sales and Marketing at Dow Key Microwave states, “As a technology leader, Dow-Key remains committed to deliver innovative switching solutions for the Test and Measurement market.” Cheung further adds, “The extensive qualification, along with the refinement of our manufacturing process for our latest Low Passive Intermodulation (PIM) switches, has enabled Dow-Key to build a solid foundation focused on the cutting edge of technology, and in areas directly in line with our customers’ needs.”

The white paper focuses on defining Passive Intermodulation and the concerns around PIM. It also discusses the cause of PIM in both general terms and in switches, while also providing a solution for systems with low PIM requirements.
