CHPFL-0500

Overview

The CHPFL-0500 is a high-pass RF filter manufactured by Crystek Corporation, designed for signal conditioning applications. It features a 7th-order Butterworth response with a cutoff frequency of 500 MHz and operates within a bandwidth extending to 3 GHz. The component maintains a 50 Ohm impedance and utilizes SMA connectors for inline mounting. 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.
• Ensures consistent signal integrity with a fixed 50 Ohm system impedance.
• Facilitates direct integration into test setups via rugged SMA connector interfaces.

Applications

• Test equipment signal conditioning
• General laboratory use
• Radio frequency circuit filtering

Procurement Notes

Verify the specific SMA connector gender (F or M) required for your application, as availability may vary between female and male variants within the same series. Confirm that the 500 MHz cutoff frequency aligns with your system requirements. Ensure the operating environment remains within the specified -40°C to +85°C thermal limits to maintain performance specifications.

Selection Notes

Select this component when a sharp roll-off is necessary above 500 MHz while maintaining low insertion loss in the passband. The inline form factor suits space-constrained designs requiring direct cable connection. Consider the 7th-order complexity if higher out-of-band rejection is critical compared to lower-order alternatives in the CHPFL series.

Part Context

This part belongs to the CHPFL series of high-pass filters from Crystek Corporation. The series offers various cutoff frequencies ranging from 50 MHz to 1 GHz, all sharing similar construction standards. These filters are distinct from low-pass variants like the CLPFL series and are specifically optimized for rejecting lower-frequency noise in RF paths.

Replacement Considerations

Direct substitutes include other CHPFL models with identical 500 MHz cutoff ratings if connector gender differs. Cross-series replacement requires verifying that the alternative component matches the 7th-order response curve and 50 Ohm impedance to ensure circuit compatibility without retuning.
