AFII-LC-0049-Q

Overview

The AFII-LC-0049-Q is a surface-mount band-pass filter designed for ultra-wideband (UWB) applications. It operates within a frequency range of 6.2 GHz to 7.8 GHz, centered at 7 GHz with a bandwidth of 1.6 GHz. The component features an insertion loss of 0.9 dB and handles up to 3W of power. Packaged in a compact 0805 [2012 Metric] footprint with four pins, it maintains a 50 Ohm impedance. This device is AEC-Q200 qualified and supports operation from -40°C minimum temperature.

Feature Summary

• AEC-Q200 qualified for automotive reliability standards
• High-rejection ceramic construction for signal integrity
• Compact 0805 surface-mount package design

Applications

• Automotive UWB systems
• Secure car access
• Real-time location systems
• Indoor navigation
• Hands-free payment

Procurement Notes

Verify the specific suffix 'Q' confirms AEC-Q200 qualification status. Ensure the 0805 package dimensions align with PCB layout requirements. Confirm the 3W power handling meets system thermal constraints. Validate the 6.2 GHz to 7.8 GHz passband against target UWB channel specifications. Check termination style compatibility with assembly processes.

Selection Notes

Select this component for high-frequency filtering where automotive grade reliability is mandatory. The 0.9 dB insertion loss offers efficient signal transmission within the specified band. Consider the 0805 size for space-constrained designs requiring robust RF performance. Evaluate the 3W power rating against peak signal levels in the application environment.

Part Context

This part belongs to Abracon's high-rejection band-pass ceramic filter series. It targets the growing demand for secure short-range wireless communication in vehicles. The UWB focus distinguishes it from standard Bluetooth or Wi-Fi filters in the same product family.
