In the field of radio frequency and microwave signal transmission, in addition to the transmission of wireless signals that do not require transmission lines, most scenarios still require the use of transmission lines for signal conduction. Coaxial lines and waveguides are widely used to transmit microwave and radio frequency energy. In order to be used in various situations, these two transmission lines sometimes need to be connected to each other, which requires a coaxial waveguide converter.

Coaxial waveguide converters are indispensable passive conversion devices in various radar systems, precision guidance systems and test equipment. They have the characteristics of wide frequency band, low insertion loss and small standing wave. The bandwidth of coaxial lines and waveguides is relatively wide when they are transmitted separately. After being connected, the bandwidth depends on the converter, that is, it depends on the matching of the characteristic impedance of the coaxial waveguide. Coaxial waveguide conversion is also commonly used in many microwave systems, such as antennas, transmitters, receivers, and carrier terminal equipment.

The waveguide to coaxial converter is mainly composed of a first converter, a second converter and a flange, and the three components are connected in sequence. There are two structures: orthogonal 90° waveguide to coaxial converter and terminated 180° waveguide to coaxial converter, which can be selected according to different usage scenarios.

The working frequency range of the waveguide to coaxial converters we can currently supply is 1.13-110GHz, which are widely used in civil, military, aerospace, testing and measurement fields, etc. They can also be customized and produced according to customer requirements.
