AM428B1048

Overview

The AM428B1048 is a ceramic band pass filter manufactured by Anatech Electronics Inc. It operates with a center frequency of 428.5 MHz and provides a bandwidth of 33 MHz. The component features a 50 Ohm impedance rating and is housed in a 12-SMD module package. This device is designed for radio frequency applications requiring precise signal filtering within the specified frequency range.

Feature Summary

• Utilizes ceramic technology for stable RF filtering performance
• Designed as a band pass filter to isolate specific frequency ranges
• Constructed in a surface mount module format for integration

Applications

• Radio frequency signal processing systems
• Microwave communication equipment
• Military and commercial RF filter applications

Procurement Notes

Verify the exact center frequency and bandwidth specifications against the official datasheet before procurement. Confirm that the 12-SMD package dimensions are compatible with your PCB layout. Ensure the 50 Ohm impedance matches your system requirements. Check for RoHS compliance status if required by your manufacturing standards. Validate the manufacturer part number to avoid substitution errors.

Selection Notes

Select this component when a fixed center frequency of 428.5 MHz is required. The 33 MHz bandwidth defines the selectivity of the filter. Consider the 12-SMD package size for space-constrained designs. Ensure the 50 Ohm impedance aligns with source and load impedances. Verify thermal and mechanical constraints for the operating environment.
