RF Directional Couplers Procurement Notes

This component is officially classified as obsolete or end-of-life by the manufacturer. Procurement should focus on verifying availability through authorized distributors or secondary market channels. Buyers must confirm the specific suffix variant matches their design requirements, as legacy stock may vary in condition. Engineering teams should initiate replacement strategies immediately to ensure long-term supply chain stability for production schedules.

RF Directional Couplers Selection Notes

Engineers selecting this part must verify that the 750MHz operating frequency aligns with their system requirements. The 50W power rating and 20dB coupling factor are critical parameters for circuit design. Due to the obsolete status, alternative components from the same series or competing manufacturers should be evaluated for pin compatibility and electrical equivalence to maintain design continuity without re-certification delays.

RF Directional Couplers Part Context
