Directional Couplers

Discontinued Product...Only available while supplies last!

0.5 to 2.0 GHz

This series of directional couplers feature high directivity

and low SWR and are conservatively rated to ensure the

most reliable service and performance under severe envi-

ronmental conditions. These designs are ideal for lab

applications, internal leveling, ECM Systems, communica-

tion satelites, RF and microwave test equipment, and

wireless applications. Other features include:

Selection of Coupling Factors:

20 & 30 dB

Female SMA Connectors:

Rugged 4 hole connector

construction insures mechanical superiority

Temperature Range:

-55˚C to +85˚C
