Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm tape-and-reel packaging requirements. Ensure that the selected variant matches the exact electrical specifications required for the target circuit design. Cross-reference the part number with authorized distributors to confirm current availability status and compliance with regional supply restrictions. Confirm that the component meets all necessary environmental certifications for the intended deployment environment.

Selection Notes

Select this component based on its specific 10.6 GHz center frequency and 1.2 GHz bandwidth requirements. Evaluate the 2 dB insertion loss against system sensitivity constraints to ensure adequate signal integrity. Consider the 50 Ohm impedance matching for compatibility with standard RF transmission lines. Assess the thermal performance capabilities within the specified -55°C to +125°C operational range for the application environment.
