CLPFL-1200

Overview

The CLPFL-1200 is a low-pass RF filter manufactured by Crystek Corporation, designed for signal conditioning applications. It operates within a frequency range of DC to 1,200 MHz and features a 7th-order Butterworth response. The component maintains a system impedance of 50 Ohms and utilizes SMA connectors with axial termination. It is engineered to function reliably across an operating temperature range of -40°C to 85°C.

Feature Summary

• Provides steep attenuation characteristics through a 7th-order Butterworth filter response design.

Applications

• RF signal conditioning in communication systems
• Harmonic suppression in radio frequency circuits
• Interference filtering in test and measurement equipment

Procurement Notes

Verify the specific connector configuration (female or male SMA) required for your assembly, as sources indicate availability in both variants. Confirm the axial termination style matches your PCB layout constraints. Ensure the operating environment stays within the specified -40°C to 85°C thermal limits to maintain performance integrity.

Selection Notes

Select this component when a sharp cutoff near 1.2 GHz is required with minimal passband ripple due to the Butterworth topology. The 50-Ohm impedance ensures compatibility with standard RF transmission lines. Consider the physical axial package dimensions during mechanical integration planning.

Part Context

This part belongs to the CLPFL series of low-pass filters from Crystek Corporation. Other models in this family, such as the CLPFL-1000 and CLPFL-1400, share similar 7th-order Butterworth response characteristics but differ in their specific cutoff frequencies, allowing for tailored frequency selection across various RF bands.

Replacement Considerations

Direct substitutes within the same series include CLPFL-1000 and CLPFL-1400, which offer identical filter responses but different cutoff frequencies. Verify that the alternative part's frequency specification aligns with the specific spectral requirements of the application before substitution.
