RBP-98+

Overview

The RBP-98+ is a lumped LC bandpass filter manufactured by Mini-Circuits, designed for radio frequency applications. It features a center frequency of 103 MHz with a bandwidth of 56 MHz, covering a passband from 75 to 131 MHz. The component operates at a nominal impedance of 50 ohms and utilizes an SMD surface-mount package without leads.

Feature Summary

• Lumped LC construction for compact form factor
• Surface-mount technology (SMT) design
• Integrated metal shielding

Applications

• RF signal filtering in communication systems
• IF stage filtering in receivers
• General-purpose RF circuit integration

Procurement Notes

Verify the specific ordering suffix against the official Mini-Circuits datasheet to ensure correct packaging and tape-and-reel specifications. Confirm that the required evaluation board, such as the 98-PL-176, is available if testing is needed prior to final implementation. Ensure compatibility with standard SMD assembly processes.

Selection Notes

Select this component when a narrow bandpass response centered at 103 MHz is required within a limited PCB area. The 50-ohm impedance matches standard RF transmission lines. Consider the SMD package type for automated assembly needs. Verify that the 56 MHz bandwidth adequately covers the desired signal spectrum while rejecting out-of-band interference.

Part Context

This part belongs to the Mini-Circuits RBP series of lumped element bandpass filters. These components are engineered for high performance across RF and IF frequencies. The '+' suffix typically indicates lead-free compliance according to RoHS standards, aligning with modern environmental manufacturing requirements.

Replacement Considerations

Consult the Mini-Circuits database for direct substitutes with identical electrical characteristics. Alternative models may offer different bandwidths or center frequencies. Ensure any replacement maintains the 50-ohm impedance and compatible SMD footprint to avoid redesigning the PCB layout.
