BPF-B177+

Overview

The BPF-B177+ is a surface-mount bandpass filter from Mini-Circuits designed for RF signal conditioning. It operates within a passband of 170 to 185 MHz, centered at 177 MHz with a bandwidth of 15 MHz. The component features a 50-ohm impedance and utilizes a 6-SMD, no-lead package measuring 20.98mm x 11.99mm x 5.59mm. It supports storage temperatures ranging from -65°C to 150°C.

Feature Summary

• Provides selective frequency filtering within the specified S-band range
• Designed for surface-mount integration into compact circuit boards
• Maintains 50-ohm system impedance compatibility

Applications

• S-band upconverter assemblies
• Radar systems
• Electronic warfare equipment
• Navigation systems

Procurement Notes

Verify the specific datasheet version (e.g., URJ/RAV) against your design requirements. Confirm that the 6-SMD package dimensions align with your PCB footprint. Ensure thermal management strategies accommodate the specified operating temperature range during final assembly and operation.

Selection Notes

Select this component when a fixed center frequency near 177 MHz is required. The narrow 15 MHz bandwidth makes it suitable for applications needing precise spectral isolation. Consider the physical size constraints of the 6-SMD package relative to available board space.

Part Context

This part belongs to the Mini-Circuits BPF series of bandpass filters. These components are engineered for high-performance RF and microwave applications. The series offers various center frequencies to support different communication standards and radar bands.

Replacement Considerations

Check Mini-Circuits documentation for other models in the BPF series with similar center frequencies. Verify that any substitute maintains the same 50-ohm impedance and compatible package outline to ensure direct interchangeability.
