AM1090B1181

Overview

The AM1090B1181 is a ceramic band pass filter manufactured by Anatech Electronics Inc. It operates at a center frequency of 1090 MHz with a 50Ω impedance. The device features a bandwidth of 30 MHz and insertion loss of less than 3.0 dB. It provides greater than 55 dB attenuation at 970 MHz and over 32 dB rejection at frequencies plus or minus 70 MHz from the center.

Feature Summary

• Utilizes ceramic construction for stable RF filtering performance
• Designed for precise band pass applications in microwave circuits
• Provides high out-of-band rejection capabilities

Applications

• Aviation transponder signal processing
• ADS-B receiver front ends
• RF monitoring systems operating near 1090 MHz

Procurement Notes

Verify the specific datasheet version to confirm exact electrical tolerances and physical dimensions before integration. Ensure the supplier provides original manufacturer documentation to validate authenticity. Check for any specific handling requirements related to ceramic components during assembly.

Selection Notes

Select this component when a fixed center frequency of 1090 MHz is required with moderate bandwidth. Consider the 50Ω impedance match for standard RF systems. Evaluate the attenuation specifications against system noise floor requirements to ensure adequate interference rejection.

Part Context

Anatech Electronics specializes in RF and microwave filters. This part belongs to their ceramic band pass filter series, designed for reliable performance in demanding electronic environments. The company focuses on custom and standard filter solutions for communication and sensing applications.

Replacement Considerations

Consult official substitution lists for equivalent models with matching center frequencies and bandwidths. Verify that alternative parts maintain the same 50Ω impedance and physical footprint to ensure compatibility with existing PCB layouts.
