LP0805H2900ASTR

Overview

The LP0805H2900ASTR is a high-performance low-pass RF filter manufactured by KYOCERA AVX. It operates at a center frequency of 2.9 GHz with a nominal impedance of 50 ohms. The component utilizes thin-film technology and is housed in an 0805 (2012 metric) surface-mount package measuring 2.03mm x 1.55mm x 1.05mm. Key electrical specifications include a maximum insertion loss of 0.95 dB and a rejection level of 25 dB. It functions within a temperature range of -40°C to +85°C.

Feature Summary

• High rejection performance of 25 dB for effective signal filtering
• Low insertion loss of 0.95 dB maximum for minimal signal attenuation
• Compact 0805 surface-mount footprint for space-constrained designs
• Thin-film construction ensuring stability across wide temperature ranges

Applications

• RF front-end modules requiring low-pass filtering
• Wireless communication systems operating near 2.9 GHz
• Signal conditioning circuits in mobile devices
• Test and measurement equipment interfaces

Procurement Notes

Verify the specific datasheet version when ordering, as manufacturers may update documentation without changing the core part number. Confirm RoHS compliance status directly with the supplier or manufacturer representative prior to final procurement decisions. Ensure that the required packaging format matches your assembly line capabilities, as availability varies between cut tape and reel formats depending on the distributor.

Selection Notes

Select this component when a compact low-pass filter is needed for frequencies around 2.9 GHz. The 0805 package size suits applications where board real estate is limited. Consider the 0.95 dB insertion loss specification against system link budget requirements. Verify that the 50-ohm impedance matches the surrounding circuitry to prevent signal reflection issues during integration.

Part Context

This part belongs to the LP series of high-performance thin-film filters from KYOCERA AVX. These components are designed for RF and microwave applications requiring precise frequency control. The series offers various cutoff frequencies while maintaining consistent physical dimensions and electrical characteristics suitable for modern electronic devices.
