RBP-253+

Overview

The RBP-253+ is a lumped LC bandpass filter manufactured by Mini-Circuits, designed for radio frequency signal conditioning. It operates within a frequency range of 186 MHz to 340 MHz, providing a bandwidth of 154 MHz with a center frequency of 253 MHz. The component features a 50 Ohm impedance and utilizes an SMD/SMT termination style in an 8-SMD, No Lead package. It is rated for an operating temperature range of -40°C to 85°C.

Feature Summary

• Lumped LC construction for compact RF filtering
• Bandpass characteristic centered at 253 MHz
• Surface mount termination for automated assembly

Applications

• RF signal conditioning circuits
• Radio frequency interference suppression
• Communication system front-end filtering

Procurement Notes

Verify the specific datasheet version and electrical parameter tolerances against your design requirements before procurement. Confirm that the 8-SMD, No Lead package dimensions align with your PCB footprint constraints. Ensure the operating temperature range of -40°C to 85°C meets your environmental specifications. Cross-reference the impedance value of 50 Ohms with your system interface standards to prevent mismatch issues.

Selection Notes

Select this component when a fixed center frequency of 253 MHz with a 154 MHz bandwidth is required. The lumped LC topology offers a compact solution compared to distributed line filters. Consider the SMD package type if surface mount assembly is preferred. Verify that the 50 Ohm impedance matches the source and load impedances in the signal path to ensure optimal power transfer and minimal reflection.

Part Context

This part belongs to Mini-Circuits' lineup of RF and IF components, which span from DC to 86 GHz. The RBP series specifically addresses bandpass filtering needs using lumped element designs. These components are engineered for consistent performance in demanding RF environments, supporting various communication and instrumentation applications requiring precise frequency selection.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Evaluate alternative bandpass filters with similar center frequencies (253 MHz) and bandwidths (154 MHz) only after verifying impedance and package compatibility.
