AFII-LC-0049

Overview

The AFII-LC-0049 is a band-pass filter designed for Ultra-Wideband (UWB) applications, operating within a frequency range of 6.2GHz to 7.8GHz with a center frequency of 7GHz. It features a 1.6GHz bandwidth and low insertion loss of 0.9dB. The component utilizes LTCC technology in an 0805 [2012 Metric] package measuring 2.0 x 1.25 x 0.95 mm. It has four pins, single-ended input/output, and a 50 Ohm impedance.

Feature Summary

• Supports UWB channels 5-8
• Compact size suitable for space-constrained designs
• Single-ended input and output configuration
• Excellent selectivity with high out-of-band rejection

Applications

• Ultra-Wideband communication systems
• Wireless personal area networks
• Short-range high-speed data transfer devices

Procurement Notes

Verify the specific suffix if automotive or enhanced reliability grades are required, such as the AFII-LC-0049-Q variant. Confirm that the 0805 footprint matches the PCB layout. Ensure the 50 Ohm impedance aligns with system requirements. Check datasheet for temperature stability specifications before integration into harsh environments.

Selection Notes

Select this component for applications requiring precise filtering in the 6.2GHz to 7.8GHz range. The low insertion loss of 0.9dB ensures minimal signal attenuation. The compact LTCC construction supports miniaturization needs. Verify compatibility with single-ended circuit topologies rather than differential setups.

Part Context

This part belongs to Abracon's AFII-LC series of ceramic band-pass filters. The series offers various center frequencies including 1400MHz, 2450MHz, and 7245MHz. The AFII-LC-0049 specifically targets the higher frequency UWB spectrum using Low-Temperature Co-fired Ceramic technology for reliable performance.

Replacement Considerations

The AFII-LC-0049-Q is a qualified version of this component. Direct substitutes from other manufacturers require matching the 6.2-7.8GHz passband, 0805 package, and 0.9dB insertion loss specifications.
