Application Guide to RF Coaxial Connectors and Cables

August 13, 2012

There is a wide variety of coaxial connectors and cables available for use in the RF and Microwave spectrum. While often not much thought is given to these essential components, a misstep here can result in undesirable system degradation. Given that typical RF systems are comprised of any number of items, e.g. RF generators, amplifiers, attenuators, power meters, couplers, antennas, etc., it is not uncommon that a great deal of thought is given to these âhigh end devices while mundane items such as connectors and cables are often treated as an afterthought".
