Procurement Notes

Verify the specific ordering suffix and package variant against the official Mini-Circuits datasheet before procurement. Ensure compatibility with the target PCB footprint for the AT577-1 case style. Confirm that the operating frequency range of 1 MHz to 400 MHz aligns with the system requirements. Cross-reference the manufacturer part number to avoid confusion with similar series components.

Selection Notes

Select this component when a precise 75-ohm to 100-ohm impedance transformation is required in a surface-mount design. The 1:1.33 ratio is specific to this application; verify that no other ratio better suits the circuit topology. Consider the physical dimensions of the AT577-1 package during layout planning. Ensure the frequency response up to 400 MHz meets the operational bandwidth needs of the application.
