AM1090B1511

Overview

The AM1090B1511 is a ceramic band pass filter manufactured by Anatech Electronics Inc. It operates at a center frequency of 1090 MHz with a bandwidth of 12 MHz and a nominal impedance of 50 Ohms. The component features a maximum insertion loss of 6.5 dB. It provides significant rejection in adjacent bands, specifically greater than 33 dB at 1078 MHz and greater than 60 dB at 1065 MHz. The device is housed in a 16-SMD module package.

Feature Summary

• Utilizes ceramic technology for stable RF filtering performance
• Designed for precise center frequency operation at 1090 MHz
• Provides high out-of-band rejection capabilities
• Constructed in a compact surface-mount module format

Applications

• Aviation navigation systems operating at 1090 MHz
• ADS-B receiver front-end filtering
• RF signal conditioning in communication equipment
• Electronic warfare and defense applications

Procurement Notes

Verify the specific datasheet version to confirm mechanical dimensions and terminal configurations before integration. Ensure that the 16-SMD package footprint matches the design layout. Confirm thermal management requirements are met for the specified insertion loss characteristics during continuous operation.

Selection Notes

Select this component when a narrowband ceramic filter is required for 1090 MHz applications. Consider the 12 MHz bandwidth relative to system signal requirements. Evaluate the 6.5 dB insertion loss against link budget constraints. Compare rejection specifications at 1078 MHz and 1065 MHz against interference profiles.
