Procurement Notes

Verify the specific datasheet version and electrical tolerances directly with the manufacturer or authorized distributor before integration. Confirm that the 50-ohm impedance and 2.5 dB insertion loss specifications align with your system requirements. Ensure compatibility with your PCB footprint and reflow soldering profiles to maintain component integrity during assembly.

Selection Notes

Select this component when a fixed 3.1 GHz center frequency with 430 MHz bandwidth is required. The 2.5 dB insertion loss indicates moderate signal attenuation, which must be accounted for in link budget calculations. Verify that the surface-mount package fits within the available board space constraints.
