High-Directivity Directional Couplers Cover 1-18GHz, Useable 0.5-20GHz.

 

Werbel Microwave LLC is developing a new series of high-directivity directional couplers for laboratory use.  The series is designed to operate over the frequency band 1-18GHz but the devices are useable over 0.5-20GHz with some performance roll-off.  Currently available in 10 and 20 dB units.  Directivity is 15 dB minimum and VSWR is 1.5:1 maximum over the entire band.  Coupling flatness is +/- 0.5dB nominal within a +/- 1.0 dB window.  Made in Livingston, NJ, USA.
