BPF-A730+

Overview

The BPF-A730+ is a lumped LC bandpass filter manufactured by Mini-Circuits, designed for surface-mount applications. It operates within a frequency range of 670 MHz to 795 MHz with a bandwidth of 125 MHz. The component features a 50-ohm impedance and utilizes SMD/SMT termination types. It is housed in the HQ1157 case style, measuring 4.57 mm x 3.81 mm x 1.52 mm. The device supports a minimum operating temperature of -40°C and a maximum of +85°C.

Feature Summary

• High rejection characteristics for effective signal filtering
• Shielded case design to minimize interference
• Aqueous washable construction for manufacturing compatibility

Applications

• Wireless communication systems
• Cable television infrastructure
• Industrial control equipment
• Medical electronics

Procurement Notes

Verify the specific datasheet revision and electrical performance graphs directly from Mini-Circuits official documentation before integration. Confirm that the HQ1157 package dimensions align with your PCB footprint requirements. Ensure environmental ratings meet the operational temperature extremes of your target application environment.

Selection Notes

Select this component when a narrowband filter is required between 670 MHz and 795 MHz. The 50-ohm impedance matches standard RF transmission lines. Consider the shielded enclosure if electromagnetic interference isolation is critical. Verify that the surface-mount form factor fits the available board space constraints.

Part Context

This part belongs to the Mini-Circuits BPF series of signal conditioning components. Mini-Circuits specializes in RF, IF, and microwave devices ranging from DC to 86 GHz. The BPF-A730+ represents their lumped element technology approach to bandpass filtering solutions.

Replacement Considerations

Consult Mini-Circuits official substitution guides for verified alternatives. Do not assume functional equivalence with generic filters without verifying impedance and frequency response curves.
