The most important thing we build is trust
Reflective Switches With TTL Drivers & Removable Connectors
Features:
Description:
Cobham’s diode switches cover multi-octave bandwidths from S to Ku-
band. Cobham/s capability in both semiconductor and digital circuit
technology allows considerable flexibility in the tradeoffs of power,
speed, RF parameters and drivers. Those switches may be used as
drop-ins on stripline assemblies by removing the SMA connectors.
The removable mounting plate allows clearance when using the device
with cable assemblies. The SMA connector seals are integrated in the
housing to allow connector removal without violating the hermetic
seal.
