RBP-135+

Overview

The RBP-135+ is a lumped LC bandpass filter manufactured by Mini-Circuits, designed for surface mount applications. It operates with a center frequency of 135 MHz and provides a bandwidth of 30 MHz. The component features a 50-ohm impedance and utilizes an SMD/SMT termination type. Its physical dimensions are 8.89 mm x 8.89 mm x 2.54 mm. The device supports an operating temperature range from -40°C to +85°C and can handle an RF power input of 0.5W at 25°C.

Feature Summary

• Surface mount construction for automated PCB assembly
• Lumped LC circuit topology for compact filtering
• RoHS compliant manufacturing process

Applications

• RF signal conditioning in communication systems
• Frequency selection in receiver front-ends
• Interference rejection in test and measurement equipment

Procurement Notes

Verify the specific datasheet revision when sourcing, as electrical specifications may be updated by the manufacturer. Confirm that the package footprint matches the provided ECAD model dimensions of 8.89 mm x 8.89 mm before finalizing design integration. Ensure thermal management strategies account for the specified maximum operating temperature of +85°C during high-power operation scenarios.

Selection Notes

Select this component when a fixed 135 MHz center frequency with 30 MHz bandwidth is required in a low-profile surface mount package. The 50-ohm impedance makes it suitable for standard RF transmission lines. Consider the -40°C to +85°C operating range for environmental compatibility. Evaluate the 0.5W power handling capability against system signal levels to ensure reliable performance without degradation.

Part Context

This part belongs to the RBP series of bandpass filters from Mini-Circuits, which are characterized by their lumped LC design and surface mount packaging. The series offers various center frequencies tailored for different RF applications. The RBP-135+ specifically targets the VHF band, providing a standardized solution for engineers requiring precise frequency selection in compact electronic designs.

Replacement Considerations

Consult Mini-Circuits documentation for direct substitutes within the RBP series or alternative manufacturers offering equivalent 135 MHz bandpass filters. Verify pinout compatibility and mechanical footprint alignment before substitution. Cross-reference electrical parameters such as insertion loss and stopband attenuation to ensure functional equivalence in the target application.
