AE125H9779

Overview

The AE125H9779 is a high-pass LC filter module manufactured by Anatech Electronics Inc. Designed for RF and microwave applications, this component features a cutoff frequency of 125 MHz with an operational passband extending from 125 MHz to 1000 MHz. It provides a maximum insertion loss of 0.5 dB within the passband and maintains a minimum return loss of 15 dB. The unit offers greater than 30 dB attenuation in the stopband range of 88-110 MHz, ensuring effective signal filtering for aerospace and commercial systems.

Feature Summary

• LC high-pass filter topology designed for RF and microwave frequencies
• Operational passband coverage from 125 MHz to 1000 MHz
• Low insertion loss characteristics for efficient signal transmission
• High attenuation performance in the lower stopband region

Applications

• Aerospace communication systems
• Commercial RF infrastructure
• Microwave signal processing modules

Procurement Notes

Verify the specific datasheet version when ordering, as electrical specifications such as attenuation levels may vary between production batches. Confirm that the required package type matches your system integration needs. Ensure compatibility with operating temperatures specified in the official documentation. Cross-reference part numbers carefully to avoid confusion with similar models in the 120-1000 MHz series. Contact the manufacturer directly for detailed technical support regarding custom requirements or specific application constraints.

Selection Notes

Select this component when a fixed 125 MHz cutoff frequency is required for high-pass filtering applications. Consider the 0.5 dB maximum insertion loss limit for sensitive signal chains. Evaluate the 15 dB minimum return loss against system impedance matching requirements. Verify that the 125-1000 MHz passband aligns with the target frequency spectrum. Assess the >30 dB attenuation capability for interference rejection in the 88-110 MHz range before finalizing the design.

Part Context

Anatech Electronics Inc. specializes in designing and manufacturing RF and microwave filters for military and commercial industries. Founded in 1990, the company holds ISO 9001:2015 certification. The AE125H9779 belongs to their standard high-pass filter lineup, which includes various cutoff frequencies ranging from 120 MHz to 1000 MHz. These components are engineered for reliability in demanding aerospace and commercial environments.

Replacement Considerations

The AE120H9779 serves as a comparable alternative with a 120 MHz cutoff frequency. Both units operate within the 120-1000 MHz passband range. Verify mechanical dimensions and connector types before substitution. Electrical parameters such as insertion loss and return loss should be compared against specific application requirements to ensure functional equivalence.
