The RFFM4252TR7 from Qorvo is a highly integrated front-end module (FEM) designed for Wi-Fi 802.11a/n/ac systems operating in the 4.9 to 5.85 GHz frequency band. It combines a power amplifier (PA), a low-noise amplifier (LNA), and a transmit/receive (T/R) switch into a single compact QFN package, simplifying RF design and reducing board space.

Key Features

• Integrated PA, LNA, and T/R switch for complete front-end functionality
• Supports Wi-Fi 802.11a/n/ac standards
• Compact 4x4 mm QFN package suitable for space-constrained designs
• Operating temperature range from -40 to +85 °C
• Typical supply voltage of 3.3 V
• Designed for 5 GHz band operation (4.9-5.85 GHz)

Applications

• Wi-Fi access points and routers
• Set-top boxes and streaming devices
• IoT gateways and smart home equipment
• Industrial and commercial wireless systems

Selection Guidance

When selecting the RFFM4252TR7, verify the specific gain, noise figure, and linearity requirements of your system against the detailed datasheet. The device is suitable for designs requiring a compact, integrated front-end solution for 5 GHz Wi-Fi. Confirm interface compatibility (e.g., MIPI RFFE) and power supply levels with your system architecture.
