AFII-DF-0036

Overview

The Abracon AFII-DF-0036 is a surface-mount ceramic resonant filter designed for Wi-Fi 6E and Wi-Fi 7 coexistence applications. It operates at a center frequency of 5787 MHz with a bandwidth supporting the 5 GHz U-NII bands. The component features high out-of-band rejection to mitigate interference between adjacent wireless standards. It is rated for an operating temperature range from -40°C to +105°C and complies with RoHS directives.

Feature Summary

• Designed specifically for Wi-Fi 6E and Wi-Fi 7 coexistence scenarios
• Provides high out-of-band rejection for signal integrity
• Surface-mount device (SMD) construction for automated assembly

Applications

• Wi-Fi 6E access points and client devices
• Wi-Fi 7 network infrastructure equipment
• Multi-standard wireless communication modules requiring 5 GHz band filtering

Procurement Notes

Verify the specific datasheet version and mechanical dimensions prior to integration, as manufacturer specifications may be updated. Confirm that the SMD footprint matches the target PCB layout exactly. Ensure the operating environment remains within the specified -40°C to +105°C thermal range to maintain performance reliability. Check for any recent product change notices regarding material or process modifications.

Selection Notes

Select this component when designing systems that must simultaneously support legacy Wi-Fi 5/6 and newer 6E/7 standards in the 5 GHz spectrum. The choice depends on the requirement for compact SMD packaging and robust out-of-band attenuation. Evaluate the insertion loss characteristics against system link budget requirements. Consider the thermal rating if the device will operate in enclosed or high-ambient-temperature environments.

Part Context

This part belongs to Abracon's line of dielectric and ceramic filters intended for signal conditioning in RF front-ends. It addresses the growing need for spectral isolation in modern wireless devices where multiple protocols share overlapping or adjacent frequency allocations. The series supports manufacturers in meeting regulatory compliance and performance standards for next-generation wireless connectivity.
