BPF-A76+

Overview

The BPF-A76+ is a lumped LC bandpass filter designed for operation within the 74 to 77 MHz frequency range. It features a nominal system impedance of 50Ω and utilizes the HQ1157 shielded case style. Typical performance data indicates a Voltage Standing Wave Ratio (VSWR) of 1.3:1 at the passband center frequency. The component is engineered to provide high rejection characteristics outside the designated passband, ensuring effective signal filtering in RF applications.

Feature Summary

• Lumped LC construction optimized for specific frequency band selection
• Shielded case design to minimize external interference
• High rejection capability for out-of-band signal suppression

Applications

• RF front-end filtering
• Communication systems requiring specific band isolation
• Test and measurement equipment signal conditioning

Procurement Notes

Verify the exact part number suffix against official Mini-Circuits documentation to ensure correct specifications. Confirm that the required operating temperature range and power handling capabilities align with your system design constraints before ordering. Cross-reference the HQ1157 package dimensions with your PCB layout requirements to ensure mechanical compatibility.

Selection Notes

Select this component when a narrow bandpass response between 74 and 77 MHz is required. Consider the 50Ω impedance match for integration into standard RF transmission lines. Evaluate the typical VSWR performance against system return loss budgets. Ensure the shielded enclosure meets electromagnetic interference mitigation requirements for the intended deployment environment.

Part Context

This component belongs to the Mini-Circuits BPF series of bandpass filters. These filters are part of a broader portfolio of RF and microwave components manufactured by Mini-Circuits. The series typically includes various frequency ranges and impedance options to support diverse electronic design needs across communication and instrumentation sectors.

Replacement Considerations

Consult official Mini-Circuits substitution guides for verified alternatives. Do not assume functional equivalence with other manufacturers' parts without comprehensive electrical testing. Verify that any substitute maintains the same frequency range, impedance, and physical footprint requirements.
