Anteral’s couplers (CPL) are available in different bands covering the frequency range from 7 GHz to 110 GHz. COTSs and custom designs are available. All waveguide couplers are designed for the required coupling level with minimum insertion loss and coupling accuracy. In addition, optimized assemblies for custom coupling levels and accuracy or topologies can be requested. Couplers are widely used in test setups where p ower reflection measurements are required that might involve frequency monitoring and power sampling with minimal signal loss to the main transmission path.
