AFII-DF-0035

Overview

The AFII-DF-0035 is a bandpass dielectric filter designed for Wi-Fi 6E and Wi-Fi 7 coexistence applications. It operates at a center frequency of 5697 MHz with a bandwidth of 360 MHz, covering the 5490–5850 MHz range (U-NII-2C / U-NII-3). The component features an insertion loss of 1.1 dB and a 50 Ohm impedance. It utilizes SMD/SMT termination in an 8.7 x 4.0 x 3.0 mm package. Operating temperatures range from -40°C to +85°C or +105°C depending on specific documentation.

Feature Summary

• High out-of-band rejection capabilities for signal conditioning
• Compact surface-mount design suitable for space-constrained layouts
• RoHS compliant construction

Applications

• Wi-Fi 6E device integration
• Wi-Fi 7 device integration
• Signal line filtering in wireless communication modules

Procurement Notes

Verify the specific operating temperature rating (+85°C vs +105°C) against the manufacturer's current datasheet, as sources vary. Confirm RoHS compliance status directly with the supplier. Ensure the SMD footprint matches the 8.7 x 4.0 mm dimensions during PCB layout validation.

Selection Notes

Select this component for applications requiring precise filtering within the 5 GHz U-NII bands. Consider the 1.1 dB insertion loss impact on system gain. Verify thermal requirements against the stated -40°C to +85°C/105°C range for the target environment.
