AE1250L9258

Overview

The AE1250L9258 is a low-pass RF filter module manufactured by Anatech Electronics Inc. It features SMA connectors and utilizes an LC design topology. The component provides a passband from 100 MHz to 1250 MHz with a cutoff frequency of 1250 MHz. Insertion loss is specified at less than 2.0 dB, while return loss exceeds 14 dB. Signal rejection is maintained at a minimum of 60 dB within the frequency range of 2000 MHz to 6000 MHz.

Feature Summary

• LC low-pass filter architecture for signal conditioning
• SMA connector interface for modular integration
• High attenuation in upper frequency bands

Applications

• RF signal filtering in communication systems
• Harmonic suppression in transmitter chains
• Interference mitigation in measurement equipment

Procurement Notes

Verify the specific datasheet version (AE1250L9258.pdf) for exact mechanical dimensions and electrical tolerances before procurement. Confirm RoHS compliance status as documentation indicates potential variability. Ensure SMA connector gender and mating requirements align with system interfaces. Validate operating temperature ranges against application environmental conditions.

Selection Notes

Select this module when a sharp cutoff near 1.25 GHz is required with minimal insertion loss in the passband. The high rejection ratio above 2 GHz makes it suitable for applications demanding significant harmonic suppression. Consider the SMA interface compatibility and physical module form factor during system design integration.

Part Context

This component belongs to Anatech Electronics' series of RF low-pass filters designed for modular use. The AE1250L9258 specifically targets frequencies up to 1.25 GHz, offering a balance between passband performance and stopband rejection. It serves as a specialized passive component for radio frequency engineering tasks requiring precise spectral control.

Replacement Considerations

No public substitute part numbers are confirmed in available documentation.
