BLP-15+

Overview

The Mini-Circuits BLP-15+ is a lumped LC low-pass filter designed for RF applications. It provides a passband from DC to 15 MHz with a cutoff frequency of 17 MHz. The component operates at a characteristic impedance of 50Ω and features a maximum insertion loss of 1dB within the passband. It utilizes a BNC in-line module package, ensuring reliable connectivity for signal filtering tasks.

Feature Summary

• Rugged shielded case construction
• Lumped LC circuit topology

Applications

• Test equipment
• Laboratory use
• Transmitters and receivers
• Military and high-reliability applications

Procurement Notes

Verify the specific impedance requirement (50Ω vs 75Ω) before ordering, as Mini-Circuits offers variant models like BLP-15-75+. Confirm that the BNC in-line form factor fits the system chassis. Ensure environmental ratings meet operational standards. Cross-reference datasheet specifications for exact electrical limits.

Selection Notes

Select this model when a sharp cutoff near 15 MHz is required for baseband or low-frequency RF signals. The 50Ω impedance matches standard coaxial systems. Consider the physical dimensions of the BNC module for integration. Evaluate if the lumped LC design meets power handling needs compared to distributed alternatives.

Part Context

This component belongs to the Mini-Circuits BLP series of coaxial low-pass filters. These components are engineered for broadband performance up to microwave frequencies. The BLP-15+ specifically targets low-frequency filtering needs using discrete LC elements housed in a robust metal enclosure.

Replacement Considerations

The BLP-15-75+ serves as a direct substitute for 75Ω systems. Verify connector compatibility and impedance matching when substituting. Check cutoff frequency tolerances against original design requirements.
