The new
switch generation
Miniature RF switches
The new switch generation
Due to their compact design,
extremely robust construc-
tion and innovative locking
mechanism the test switch
3926 and the external
antenna switch 3976 from
IMS Connector Systems are
suitable for a broad range of
applications.
