RBP-400+

Overview

The RBP-400+ is a surface-mount bandpass filter manufactured by Mini-Circuits, designed for RF signal conditioning applications. It operates with a center frequency of 391 MHz and provides a bandwidth of 198 MHz. The component features a standard 50 Ohm impedance and utilizes an 8-pin SMD package measuring 8.9x8.9 mm. It exhibits an insertion loss of 1.15 dB and functions reliably within a temperature range of -40°C to +85°C.

Feature Summary

• Provides precise bandpass filtering at 391 MHz center frequency
• Utilizes compact 8-pin surface mount packaging for board integration
• Maintains stable performance across industrial temperature ranges

Applications

• RF receiver front-end filtering
• Wireless communication systems
• Test and measurement equipment

Procurement Notes

Verify the specific datasheet version against the manufacturer's official documentation to confirm exact electrical tolerances and pinout configurations. Ensure compatibility with PCB footprint dimensions of 8.9x8.9 mm during layout design. Confirm RoHS compliance status if required by project specifications.

Selection Notes

Select this component when a fixed center frequency of 391 MHz is required for signal isolation. Consider the 198 MHz bandwidth relative to the desired signal spectrum. Evaluate the 8-pin SMD form factor against available board space constraints and thermal management requirements for the target application environment.

Part Context

This part belongs to Mini-Circuits' passive RF filter portfolio, specifically the bandpass category. It complements other signal conditioning components like low-pass and high-pass filters within the same product line, supporting complete RF chain designs from DC to microwave frequencies.

Replacement Considerations

Consult official Mini-Circuits substitution guides for verified alternatives. Cross-reference center frequency and bandwidth specifications carefully before replacing.
