Procurement Notes

Verify the specific ordering suffix and package variant against official Panasonic documentation before procurement. Confirm that the component meets RoHS compliance requirements for your target market. Ensure the supply chain source provides valid authenticity guarantees, as lead times may vary significantly due to manufacturing schedules. Cross-reference the datasheet revision history to confirm current production status and availability constraints.

Selection Notes

Select this component when designing circuits requiring SPDT switching at frequencies up to 18GHz. Ensure the system design accommodates the 4.5V supply voltage requirement and 50-Ohm impedance matching. Verify that the thermal management strategy supports the specified operating temperature range. Consider the module package dimensions for PCB layout compatibility and signal path optimization in dense RF environments.
