Couplers

We offer various couplers ranging from 300MHz to 40GHz (WR2300 - WR28). Due to the size and complexity of the lower-frequency components, we do not maintain a predefined standard for these products. For specific requirements or custom configurations, such as loop couplers, please contact us directly for more information.
 

Quasar Waveguide Couplers are available either as standard items or built to specification. See table below for the specifications of our full band standard products. However if you have a requirement not addressed by these items please contact the factory for further information.
 

Please use the product selection tool to select the items you require, if you are not operating over the full specified band please advise the frequency range you require and our test engineers will optimise your parts for this range. Using the product selection tool also allows you to generate and download a data sheet for the product you have specified.
