The waveguide, along with the coaxial line, is one of the most important transmission media in any modern RF, microwave and millimeter-wave component, subassembly, and system. Due to its metal tubing configuration, the waveguide tends to be heavy and bulky, especially in low microwave frequencies. However, it is always a preferred transmission means when performance and high power are priorities. In millimeter-wave bands, it is especially true that the waveguide is widely used, and engineers will pay high attention to loss. This article will discuss the use of waveguide connectors, and present viable solutions, such as the Uni-Guide™. Download the full paper for more information.
