CA-18
AIR-LINE DIRECTIONAL COUPLER
The CA-18 is a high power type N-connectorized bidirectional coupler capable of operation to 18 GHz. This coupler features a unique air-line construction that simultaneously enables extremely low loss and high directivity. This coupler can be used for low loss and high power applications. The useable operating frequencies extend below 1 GHz for applications where calibration of the frequency response is available.
