RF Switches Procurement Notes

Verify the specific termination status and connector type against the official datasheet before integration. Confirm that the 28Vdc latching requirement aligns with your system's power delivery capabilities. Ensure environmental ratings meet the operational temperature constraints defined in the manufacturer documentation. Cross-reference the part number suffix to guarantee exact functional compatibility with existing designs.

RF Switches Selection Notes

Select this component when a high-isolation, multi-port RF switching solution is required for frequencies extending to 26.5 GHz. The terminated design simplifies circuit layout by providing matched loads on all ports. Consider the latching control interface requirements, as it differs from non-latching variants. This model is suitable for applications demanding stable signal routing without continuous power consumption for state retention.
