Latching SPDT Coaxial Switch
PART NUMBER
CR-33K
DESCRIPTION
Miniature DC–33.5GHz Latching SPDT Coaxial Switch
Series CR-33K
Series CR-33K switches are broadband SPDT, electromechanical coaxial switches
designed for application frequencies above 26.5GHz. The CR-33K offers excellent
insertion loss repeatability across the full bandwidth and ultra low intermodulation
(PIM) characteristic. The switch life is characterized at 5 million cycles. The
CR-33K is designed to switch a microwave signal from a common input to either of
the two outputs. The characteristic impedance is 50 Ohms. The switches are small
with connector spacing compatible with K connectors. The design is compatible with
the two most common mounting hole patterns.
