RF Switches Procurement Notes

Verify the specific control logic requirement (28 VDC vs. TTL) against the datasheet before ordering, as variants exist within the Ramses family. Confirm that the SMA connector orientation and terminal type match the PCB layout requirements. Ensure environmental conditions align with the specified operating temperature range. Cross-reference the exact part number suffix to guarantee compatibility with existing system designs.

RF Switches Selection Notes

Select this component when high-frequency switching up to 18 GHz is required with low insertion loss. The latching feature reduces power consumption compared to non-latching alternatives. Verify that the SMA interface meets the system's interconnect needs. Consider the bulk packaging format for assembly processes. Ensure the control voltage matches the available drive circuitry.
