SXLP-45+

Overview

The SXLP-45+ is a lumped LC low-pass filter manufactured by Mini-Circuits, designed for radio frequency applications. It provides a passband from DC to 45 MHz with a 50Ω impedance. The device features a cutoff frequency of 54 MHz and maintains a 1dB insertion loss within the passband. It is housed in an 8-SMD, no-lead surface-mount package, suitable for integration into compact RF circuits requiring signal filtering.

Feature Summary

• Lumped LC architecture for effective low-pass filtering
• Surface-mount design for automated PCB assembly
• 50Ω characteristic impedance matching

Applications

• RF signal conditioning
• Harmonic suppression
• Base station front-end filtering

Procurement Notes

Verify the specific datasheet revision and electrical test criteria before procurement. Confirm that the 8-SMD no-lead package dimensions align with your PCB footprint requirements. Ensure the operating environment remains within the component's established maximum ratings to maintain performance integrity and reliability standards.

Selection Notes

Select this component when a sharp roll-off is required below 54 MHz with minimal passband ripple. The 45 MHz bandwidth suits applications needing strict attenuation of higher frequencies. Verify that the 50Ω system impedance matches your circuit design to prevent signal reflection and ensure optimal power transfer across the specified frequency range.

Part Context

This part belongs to Mini-Circuits' SXLP series of lumped element filters. These components are engineered for high performance in RF and IF stages. The series offers various cutoff frequencies while maintaining consistent 50Ω impedance and compact SMD packaging, facilitating easy integration into modern electronic systems requiring precise frequency management.

Replacement Considerations

Consult official substitution guides for compatible alternatives. Verify that any replacement maintains identical 50Ω impedance, similar cutoff characteristics, and compatible surface-mount package dimensions to ensure seamless integration without redesigning the host circuit board or impedance matching networks.
