FAQ

Q: How to choose the right product? 

A: The selection should be made comprehensively based on the waveguide type, operating frequency band, interface specifications of the connecting devices in the actual application, and the system's requirements for insertion loss and standing wave ratio. If necessary, technical personnel can be consulted for advice.

Q: What could be the reasons for excessive insertion loss of the waveguide adapter? 

A: It might be due to loose interface connection, dirt or damage on the inner wall of the waveguide, or the product selection not matching the working frequency band. You can check the connection status, clean the interface or replace it with a suitable model.

Q: What is the minimum order quantity for OEM customized waveguide Adapters? 

A: The minimum order quantity varies for different customization requirements. The specific quantity can be negotiated and determined with the sales team.

Q: How long is the general service life of a waveguide adapter? 

Under normal usage and maintenance conditions, the service life can reach 5 to 8 years, depending on the usage environment and frequency.
