BPF-A580+

Overview

The BPF-A580+ is a lumped LC bandpass filter manufactured by Mini-Circuits, designed for RF applications. It operates within a passband of 520 MHz to 640 MHz with a nominal center frequency of 580 MHz and a bandwidth of 120 MHz. The component features a 50Ω impedance and utilizes a surface-mount 14-SMD module package (Case Style HQ1157) measuring 34.54mm x 9.27mm. Typical performance data indicates linear phase characteristics up to ±6 degrees at the center frequency plus or minus 60 MHz.

Feature Summary

• Provides high rejection outside the designated passband
• Maintains linear phase response within specified frequency offsets
• Utilizes lumped LC topology for compact surface-mount integration

Applications

• RF signal conditioning in communication systems
• Frequency selection in receiver front-ends
• Interference suppression in microwave circuits

Procurement Notes

Verify the specific datasheet revision and case style designation when ordering. Confirm that the 14-SMD surface-mount footprint matches the target PCB layout dimensions. Ensure the operating environment remains within the temperature range specified in the official Mini-Circuits documentation to maintain typical performance parameters.

Selection Notes

Select this component when a fixed 120 MHz bandwidth centered at 580 MHz is required. The lumped LC design offers a compact form factor suitable for space-constrained surface-mount assemblies. Consider the 50Ω system impedance compatibility and the specific insertion loss characteristics defined in the manufacturer's performance graphs before finalizing the circuit design.

Part Context

This component belongs to the Mini-Circuits BPF series of passive RF filters. These devices are engineered for use in radio frequency and microwave circuits where precise frequency selection is critical. The product line typically includes various topologies optimized for different frequency ranges and power handling requirements.

Replacement Considerations

Consult Mini-Circuits official documentation for verified substitute part numbers. Cross-referencing should be limited to components with identical electrical specifications and mechanical footprints as confirmed by the manufacturer.
