QPF4588ATR13

RF Front End (LNA + PA) Overview

The QPF4588ATR13 is an integrated RF front-end module designed for Wi-Fi 6 (802.11ax) systems operating in the 5 GHz band. It covers a frequency range of 5.15 GHz to 5.895 GHz, supporting general-purpose applications. The component integrates both Low-Noise Amplifier (LNA) and Power Amplifier (PA) functions within a single package. Key electrical specifications include a noise figure of 2 dB and an operating supply voltage of 5 V. It utilizes an SP2T switch configuration and is housed in a compact 24-QFN (5x3 mm) surface-mount package with exposed pads.
