AM1575B1156

Overview

The AM1575B1156 is a ceramic band pass filter manufactured by Anatech Electronics Inc. It operates at a center frequency of 1.575 GHz with a bandwidth of 20 MHz. The component features an insertion loss of less than 4.3 dB and is designed for 50 Ohm systems. It is housed in a 10-SMD module package, suitable for RF applications requiring precise frequency selection within the L1 GPS band.

Feature Summary

• Ceramic construction for stable RF performance
• Band pass filtering centered at 1.575 GHz
• Designed for 50 Ohm impedance systems

Applications

• GPS receiver front-end filtering
• RF signal processing modules
• Aerospace and defense communication systems

Procurement Notes

Verify the specific datasheet version to confirm mechanical dimensions and pinout configurations before integration. Ensure compatibility with 50 Ohm system impedance. Check for RoHS compliance status if required by your manufacturing standards. Confirm lead-free soldering recommendations for surface mount assembly processes.

Selection Notes

Select this component when a narrow 20 MHz bandwidth is required around the 1.575 GHz center frequency. The low insertion loss specification supports high-sensitivity receiver designs. The SMD package facilitates automated assembly in compact RF modules. Consider thermal stability requirements inherent to ceramic filter technologies.

Part Context

Anatech Electronics Inc. specializes in RF and microwave filters for commercial, aerospace, and defense sectors. This model belongs to their ceramic band pass filter series, targeting frequencies between 1001 and 2000 MHz. The company maintains ISO 9001:2015 certification for quality management in component design and manufacturing.

Replacement Considerations

No public substitute part numbers are confirmed for this specific model. Cross-referencing requires matching the 1.575 GHz center frequency, 20 MHz bandwidth, and 10-SMD package constraints exactly.
