LP0805A1747ASTR

Overview

The LP0805A1747ASTR is a surface-mount low-pass filter from the KYOCERA AVX LP series, designed for signal conditioning applications. It operates at a center frequency of 1747 MHz with a bandwidth of 75 MHz and maintains a system impedance of 50 ohms. The component features an insertion loss of 0.3 dB and is housed in a compact 0805 (2012 metric) package with four pads. It supports board mounting via SMD/SMT termination and functions reliably within an operating temperature range of -40°C to +85°C.

Feature Summary

• Provides harmonic suppression through low-pass filtering characteristics optimized for RF signal paths.
• Utilizes a miniature 0805 footprint to facilitate high-density circuit board layouts.
• Ensures signal integrity with low insertion loss and stable 50-ohm impedance matching.

Applications

• RF front-end modules requiring harmonic attenuation
• Wireless communication systems operating near 1.7 GHz
• Signal conditioning circuits in mobile devices

Procurement Notes

Verify the specific suffix against official datasheets to confirm exact electrical tolerances and packaging configurations. Ensure compatibility with standard reflow soldering profiles for 0805 components. Cross-reference RoHS compliance status with current manufacturer declarations before integration into regulated assemblies.

Selection Notes

Select this component when a 1747 MHz cutoff frequency and 75 MHz bandwidth are required for harmonic filtering. The 0805 package size suits designs with limited PCB real estate. Confirm that the 50-ohm impedance aligns with the surrounding RF transmission line architecture to minimize reflection losses.

Part Context

This part belongs to the KYOCERA AVX LP series of surface-mount low-pass filters. These components are engineered for RF signal conditioning, offering precise frequency control in a small form factor. The series supports various frequencies tailored for modern wireless standards, providing reliable performance in compact electronic devices.

Replacement Considerations

Consult official substitution guides for equivalent low-pass filters with matching 1747 MHz specifications and 0805 footprints. Verify that alternative parts maintain identical 50-ohm impedance and insertion loss characteristics to ensure circuit continuity without redesign.
