RF Diode Procurement Notes

Verify the specific ordering suffix to confirm package type and compliance status, as variations exist within the CLA4602 series. Confirm end-of-life status and availability through authorized distributors, as this part may be discontinued or subject to limited supply constraints. Ensure the supplier provides valid traceability documentation for hermetic packages.

RF Diode Selection Notes

Select the CLA4602-203 when a hermetically sealed PIN diode with a 15V breakdown voltage is required for Ka band limiting. Compare thermal resistance and capacitance values against circuit requirements. Consider alternative suffixes if non-hermetic packaging or different electrical tolerances are acceptable for the specific application design.
