CLPFL-0900

Overview

The CLPFL-0900 is a low-pass RF filter manufactured by Crystek Corporation, designed for signal conditioning applications within the DC to 900 MHz frequency range. It features a 7th-order Butterworth response and maintains a 50 ohm impedance. The component operates across an extended temperature range of -40°C to +85°C. Key electrical specifications include an insertion loss between 0.06 dB and 0.87 dB, with rejection capabilities ranging from 1.96 dB to 49.01 dB. It utilizes SMA connectors for both female and male interfaces.

Feature Summary

• Provides 7th-order Butterworth response for precise signal filtering
• Operates effectively within the DC to 900 MHz bandwidth
• Supports wide industrial temperature environments from -40°C to +85°C

Applications

• RF signal conditioning in communication systems
• Interference suppression in radio frequency circuits
• Signal integrity maintenance in broadband equipment

Procurement Notes

Verify the specific connector configuration required, as the datasheet indicates availability with both female and male SMA connections. Confirm that the operating environment falls within the specified -40°C to +85°C range to ensure optimal performance. Ensure system impedance matches the 50 ohm specification of the filter to prevent signal reflection issues during integration.

Selection Notes

Select this component when a sharp cutoff characteristic near 900 MHz is required without excessive passband ripple due to its Butterworth design. Consider the inline form factor and SMA interface compatibility with existing PCB or cable assemblies. Evaluate the thermal requirements against the stated operating temperature limits before deployment in high-heat environments.

Part Context

This part belongs to the CLPFL series of low-pass filters from Crystek Corporation, which are engineered for general-purpose RF applications. The series offers various cutoff frequencies, with the CLPFL-0900 specifically targeting sub-GHz bands. It serves as a passive component essential for managing spectral content in analog and digital RF front-ends.
