CHPFL-0300

Overview

The Crystek Corporation CHPFL-0300 is a 7th order high-pass filter designed for RF signal conditioning applications. It features a cutoff frequency of 300 MHz and operates within a 50 Ohm impedance system. The component utilizes SMA connectors for inline installation, ensuring robust connectivity in demanding environments. It is engineered to function reliably across an extended temperature range from -40°C to +85°C. This filter provides steep attenuation characteristics below the passband, effectively suppressing lower-frequency interference while maintaining signal integrity in the upper frequency spectrum.

Feature Summary

• Features a rugged SMA housing design for durable inline integration
• Provides excellent out-of-band rejection performance through 7th order filtering
• Operates within a standard 50 Ohm impedance environment

Applications

• RF signal conditioning systems requiring high-pass filtering
• Equipment operating in extreme temperature environments
• Communication infrastructure utilizing SMA connector interfaces

Procurement Notes

Verify the specific connector type and impedance requirements against your system design before procurement. Confirm that the operating temperature range meets your environmental specifications. Ensure compatibility with existing SMA interfaces. Review the official datasheet for detailed electrical performance curves and mechanical dimensions to guarantee proper integration into your RF chain.

Selection Notes

Select this component when a sharp roll-off characteristic is required above 300 MHz. The 7th order response offers superior stopband attenuation compared to lower-order alternatives. Consider the physical dimensions and SMA interface constraints during layout planning. Verify that the 50 Ohm system impedance aligns with your source and load requirements to minimize reflection losses.

Part Context

This part belongs to the Crystek CHPFL series of high-pass filters. The series includes variants with different cutoff frequencies and connector options, such as BNC or SMA. These components are designed for consistent performance in RF applications where low-frequency noise suppression is critical. The CHPFL-0300 specifically targets the 300 MHz threshold with a standardized 50 Ohm configuration.

Replacement Considerations

Direct substitutes may include other Crystek CHPFL models with similar cutoff frequencies but different connector types. Cross-manufacturer replacements require matching the 7th order response, 50 Ohm impedance, and SMA interface. Verify thermal ratings and insertion loss specifications to ensure equivalent performance in the target application.
