Procurement Notes
Verify the exact package dimensions and mounting orientation against your PCB layout requirements before integration. Confirm that the 2 dB insertion loss aligns with your system's link budget calculations. Ensure compliance with local environmental regulations regarding RoHS status. Cross-reference the manufacturer part number to avoid confusion with similar ceramic filters from other vendors.
Selection Notes
Select this component when a fixed center frequency of 5.665 GHz is required for 5.8 GHz Wi-Fi applications. Consider the 370 MHz bandwidth to ensure it covers the necessary channel spacing without excessive attenuation. Evaluate the surface mount form factor for automated assembly compatibility. Compare the 2 dB insertion loss against alternative filters to minimize signal power degradation in the transmission path.
