IW | Castle Microwaves » Castle Microwave


At Castle Microwave, we have a history of working with Cable and Cable Assembly technology. That’s why we’re proud to partner with IW.

IW's Capabilities

Founded in 1970, IW developed a unique PTFE lamination process and applied it to manufacturing wire and cable. This process allowed IW to manufacture products of unprecedented reliability along with smaller diameters. Combining the new lamination process along with a patented shield design allowed IW to become one of the leaders in low loss microwave transmission lines, utilizing both solid and expanded PTFE dielectrics. In 1988, IW expanded its operations and created the Microwave Products Division to provide turn-key standard configuration and application specific cable assemblies to an ever increasing global customer base.







Today, IW continues to work hard in developing innovative products and remains committed to providing innovative solutions for applications where reliability, size, weight, hostile environment and performance are primary considerations. Coaxial products are available in a range of diameters from 0.034" to 0.750" with assemblies available up to 67 GHz.
