CLPFL-0700

Overview

The CLPFL-0700 is a 7th-order Butterworth low-pass RF filter manufactured by Crystek Corporation. It operates with a cutoff frequency of DC to 700 MHz and maintains a system impedance of 50 Ohms. The device features an inline mechanical configuration with SMA female-to-male connectors, allowing for direct cable integration. It supports an operating temperature range from -40°C to +85°C. Key electrical specifications include an insertion loss ranging from 0.04 dB to 0.69 dB and rejection levels between 1.39 dB and 48.67 dB. The unit measures 0.435 inches in diameter by 1.504 inches in length.

Feature Summary

• Seventh-order Butterworth response design ensures steep attenuation characteristics beyond the cutoff frequency.
• Rugged housing construction provides durability for reliable signal conditioning in demanding environments.
• Inline free-hanging mounting style facilitates straightforward integration into existing RF transmission lines.

Applications

• RF signal conditioning within communication systems requiring out-of-band interference suppression.
• Test and measurement equipment setups utilizing standard 50-ohm coaxial interfaces.
• Base station front-end filtering applications where compact inline form factors are required.

Procurement Notes

Verify that the specific order suffix matches the required connector gender combination, as the standard designation implies SMA female-to-male connectivity. Confirm the active product status with the manufacturer or authorized distributors before finalizing procurement plans. Ensure environmental ratings align with the intended operational temperature range of -40°C to +85°C. Cross-reference the part number against official Crystek documentation to avoid confusion with similar series components.

Selection Notes

Select this component when a 700 MHz cutoff frequency with high out-of-band rejection is necessary. The 50-ohm impedance rating suits standard RF infrastructure. Consider the physical dimensions of 0.435 inches diameter and 1.504 inches length for spatial constraints. The inline SMA interface eliminates the need for additional adapters. Evaluate the insertion loss specifications against system sensitivity requirements to ensure signal integrity is maintained within acceptable limits.

Part Context

This component belongs to the CLPFL series of low-pass filters produced by Crystek Corporation. The series is characterized by rugged housings and excellent out-of-band rejection capabilities. These filters are designed for signal conditioning tasks across various radio frequency applications. The CLPFL-0700 specifically targets frequencies up to 700 MHz, distinguishing it from higher-frequency variants like the CLPFL-0800 or CHPFL-1000 within the broader product portfolio.

Replacement Considerations

No public confirmed substitute part numbers are available for this specific model. Engineers should verify compatibility with existing SMA interfaces and 50-ohm system impedances if considering alternative manufacturers. Direct replacement requires matching the 7th-order Butterworth response and physical inline dimensions to maintain system performance without modification.
