RF Switches Procurement Notes
Verify the specific datasheet version for the SEMS-4056-SPDT-N to confirm mechanical dimensions and electrical ratings. Ensure compatibility with existing N-type connector interfaces. Check current availability status as supply levels may fluctuate. Confirm that the 28V coil voltage requirement aligns with system control logic before finalizing procurement orders.
RF Switches Selection Notes
Select this component when high power handling and wide bandwidth are required. The failsafe mechanism ensures predictable states during power loss. Compare against semiconductor switches if lower power or faster switching speeds are needed. Verify that the physical size fits within the enclosure constraints of the target assembly.
RF Switches Part Context
This part belongs to Fairview Microwave's line of coaxial switches. It complements other RF components like adapters and amplifiers. The product series focuses on robust electromechanical solutions for demanding environments. It serves as a critical interconnect element in complex RF signal chains requiring high isolation and power tolerance.
RF Switches Replacement Considerations
SEMS-4055-SPDT-K is a related model but operates at higher frequencies up to 40 GHz with different connector types. Direct substitution requires verifying interface compatibility and power ratings. No identical direct substitutes are publicly confirmed for this specific N-type 12.4 GHz variant.
