BP0805A1795ASTR250

Overview

The BP0805A1795ASTR250 is a surface-mount bandpass RF filter from the KYOCERA AVX BP series, housed in an 0805 (2012 metric) package. It operates at a center frequency of 1.795 GHz with a bandwidth of 20 MHz. The component features a 50-ohm impedance and exhibits an insertion loss of -1.8 dB. Designed for board mounting, it functions within a temperature range of -40°C to +85°C.

Feature Summary

• High-performance surface-mount construction
• Low insertion loss characteristics
• Steep roll-off response
• High rejection of out-of-band signals

Applications

• Wireless communication systems
• RF signal conditioning circuits
• Mobile device front-end modules

Procurement Notes

Verify the specific suffix '250' against official datasheets to confirm packaging quantity or variant distinctions. Ensure compatibility with standard SMD reflow processes. Confirm RoHS compliance status for environmental regulations. Validate pinout and footprint dimensions against PCB layout requirements before integration.

Selection Notes

Select this component for applications requiring precise filtering at 1.795 GHz. Consider the 0805 footprint for space-constrained designs. Evaluate the -1.8 dB insertion loss against system power budgets. Ensure operating temperatures remain within the specified -40°C to +85°C range for reliable performance.

Part Context

This part belongs to the BP series of MLO™ bandpass filters by KYOCERA AVX. These components are engineered for high-performance RF applications, offering compact surface-mount solutions. The series is characterized by low insertion loss and steep roll-offs, making them suitable for modern wireless infrastructure and consumer electronics.

Replacement Considerations

Check for direct substitutes within the BP series with similar center frequencies. Verify that alternative parts match the 0805 package size and 50-ohm impedance. Ensure replacement components meet the same bandwidth and insertion loss specifications for circuit compatibility.
