Agilent will discontinue the sale of the 11691D and 11692D direction couplers on June 1, 2009. The support life will end on May 31, 2012. The recommended replacement for the 11691D is 773D and the 772D replaces the 11692D. The 773D and 772D provide comparable specifications at a lower cost, but with a slightly different look and dimension.

The Agilent 11691D is a single coupler for 2 to 18 GHz with a 20 dB coupling factor. With 30 dB directivity to 8 GHz and 26 dB to 18 GHz, it is useful for broadband reflectometry. It features many connector options to match test device requirements.
