CA-40_AIR-LINE DIRECTIONAL COUPLER

General Description

The CA-40 is a low loss directional coupler capable of operation to 40 GHz. This coupler features a unique air-line construction that simultaneously enables extremely low loss, minimal return loss, and outstanding directivity throughout the entire frequency range to 40 GHz. 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.
