BP0805A1457ASTR250

Overview

The BP0805A1457ASTR250 is a bandpass RF filter manufactured by KYOCERA AVX, designed for precise frequency filtering in radio frequency applications. It operates with a center frequency of 1.457 GHz and features a bandwidth of 20 MHz. The component exhibits an insertion loss of -1.5 dB at the center frequency. Housed in an 0805 (2012 Metric) surface-mount package, it is engineered for integration into compact electronic systems requiring high-performance signal conditioning.

Feature Summary

• High-performance surface-mount construction suitable for automated assembly processes
• Low insertion loss characteristics ensuring efficient signal transmission
• Steep roll-off and high rejection capabilities for effective noise suppression

Applications

• Radio frequency signal conditioning circuits
• Wireless communication system front-ends
• Precision frequency filtering in RF modules

Procurement Notes

Verify the specific suffix '250' against official manufacturer documentation to confirm packaging or variant distinctions. Ensure compatibility with standard 0805 footprint dimensions during PCB layout. Confirm RoHS compliance status through current datasheets before procurement. Validate operating temperature ranges against application requirements.

Selection Notes

Select this component when a 1.457 GHz center frequency with 20 MHz bandwidth is required. Consider the 0805 package size for space-constrained designs. Evaluate the -1.5 dB insertion loss against system sensitivity needs. Ensure the steep roll-off meets interference rejection specifications for the target RF environment.

Part Context

This part belongs to the MLO™ Band Pass Filter series from KYOCERA AVX. These filters utilize integrated thin-film technology for robust performance. The series offers various frequency options compatible with high-frequency wireless systems. They are designed for board mount installation using standard surface-mount techniques.

Replacement Considerations

Consult official substitution guides for equivalent bandpass filters with matching 1.457 GHz center frequency and 0805 footprint. Verify electrical parameters such as bandwidth and insertion loss match original specifications.
