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:
o
Selection of Coupling Factors:
20 & 30 dB
o
Female SMA Connectors:
Rugged 4 hole connector
construction insures mechanical superiority
o
Temperature Range:
-55˚C to +85˚C
