The Agilent 11692D is a dual directional coupler that samples and monitors RF signals across 2.0 GHz to 18 GHz. It measures forward and reflected power in a single device, delivering the high directivity and low insertion loss required for accurate reflectometer applications. This coupler integrates into swept-frequency test systems and broadband RF measurement setups.
