Procurement Notes
Verify availability status directly with the manufacturer or authorized distributors as stock levels fluctuate. Confirm RoHS compliance details and REACH SVHC status through official documentation before procurement. Ensure the specific ordering suffix matches the required connector type and termination style. Check for any regional sales restrictions or shipping limitations applicable to your location. Validate lead times for non-stock items to align with project schedules.
Selection Notes
Select this component when a high-frequency SP4T switching solution with latching capability is required. The 18 GHz operational range suits applications demanding wide bandwidth performance. Consider the 28 VDC drive requirement for power supply design compatibility. Evaluate the SMA interface against system connectivity standards. Compare electrical parameters like VSWR and isolation against specific signal integrity requirements.
