MSPDT: M Version Single Pole Double Throw
The MSPDT series coaxial switches are used to switch a microwave signal from a common input to either of the two outputs. They have an operating temperature range –54oC to +85oC. Characteristic impedance of the switches is 50 Ohms. Failsafe and latching switching modes are available, with other options including position of indicator contacts, standard or narrow body size and choices of connectors. SeeModel Numbering System for details.
