The Agilent HP 11691D is a single coupler for 2 to 18GHz with a 20dB coupling factor. With 30dB directivity to 8GHz and 26dB to 18GHz, the 11691D is useful for broadband reflectometry. It will also feature many connector options to match test device requirements. This unit is a three port passive device. Directional couplers sample power flowing in one direction in the mainline and reject power flowing in the opposite direction. They may be used for measurement purposes or for power leveling.
•Wide frequency coverage simplifies testing
•Ideal for leveling broadband sources
