Procurement Notes
Verify the specific suffix designation to confirm exact electrical tolerances and physical interface requirements against the official datasheet. Ensure compatibility with existing chassis mounting hardware and thermal management solutions. Confirm RoHS compliance status if required by regulatory standards. Cross-reference part numbers with authorized distributors to avoid counterfeit components.
Selection Notes
Select this component when a fixed 802 MHz center frequency with narrow 8 MHz bandwidth is required. Consider the physical footprint constraints due to the large module size. Evaluate the need for chassis mounting versus other form factors. Assess whether the specified insertion loss meets system sensitivity requirements.
