Most of the signal transmission in the field of RF and microwave requires transmission lines for signal transmission, in which coaxial lines and waveguides are widely used to transmit microwave RF energy. There are huge differences in size, material, and transmission characteristics between the two transmission lines. Therefore, a double ridge waveguide to coaxial adapter is required to interconnect the two transmission lines.
The double-ridge waveguide to coaxial adapters provides broadband capability in a very compact form and allows transmission of power in either direction with very low reflection. It plays an indispensable role in various radar systems, precision guidance systems, and test equipment.
The double ridge waveguide to coaxial adapters is used to provide transmission between microwave devices and a coaxial component such as an attenuator, switches, or couplers. Thede microwave waveguide components are commonly used in satellite and terrestrial communications equipment.
