Teflon Coaxes

Coaxes utilizing a PTFE dielectric and FEP Jacket have long been used in Military and high-end electronic devices due to their excellent electrical properties as well their ability to handle higher temperatures and increased mechanical abuse when compared to typical coaxes built with a Polyethylene dielectric and PVC Jacket.

In response to the requests from many of our customers in the RF Community as well as commercial cable assembly companies, Davis RF is pleased to offer a selection of the most common 50 and 75 Ohm Teflon Coaxes from stock.
