SLP-23+

Overview

The SLP-23+ is a Mini-Circuits lumped LC low-pass filter designed for RF signal conditioning. It provides a passband from DC to 23 MHz with a 50Ω impedance. The device features an SMA connector and operates within a temperature range of -40°C to 85°C. It supports a maximum RF power input of 0.5W and exhibits a typical attenuation rate of 1.35 (20dB/3dB bandwidth ratio).

Feature Summary

• Lumped LC architecture utilizing miniature high-Q capacitors and wire-welded inductors.
• Rugged, shielded coaxial construction for reliable signal integrity.
• SMA connector interface for direct integration into RF systems.

Applications

• RF signal conditioning in communication equipment.
• Harmonic suppression in frequency upconverter assemblies.
• General-purpose filtering in test and measurement instrumentation.

Procurement Notes

Verify the specific datasheet version and environmental rating (ENV105) before procurement. Confirm that the operating temperature range (-40°C to 85°C) aligns with your system requirements. Ensure the 0.5W maximum RF power input is sufficient for your application to prevent component damage. Check for any specific ordering suffixes if different configurations are required.

Selection Notes

Select the SLP-23+ when a sharp cutoff below 23 MHz is required with minimal insertion loss in the passband. Its rugged shielded design makes it suitable for environments requiring electromagnetic interference protection. Consider the 50Ω impedance match for standard RF systems. Evaluate the thermal performance against the specified operating temperature limits.

Part Context

The SLP-23+ belongs to Mini-Circuits' SLP series of 50Ω coaxial low-pass filters. This series utilizes lumped LC elements to achieve compact form factors while maintaining high performance. Similar models in the series offer varying cutoff frequencies, allowing designers to tailor filter characteristics to specific bandwidth needs without changing the physical package style.

Replacement Considerations

The BLP-23+ is a comparable 50Ω low-pass filter covering DC to 23 MHz. Verify if the connectorized package type matches your system requirements. Ensure the electrical specifications, particularly the cutoff frequency and impedance, remain compatible with your existing circuit design.
