2.4 GHz WiFi Power Amplifier Preliminary Datasheet-Rev01

2.4 GHz WiFi Power Amplifier

Introduction

The EPA2018A is a three-stage linearized power amplifier optimized for 802.11b/g/n wireless LAN(WLAN) applications in the 2.4 GHz band. It features 33 dB of gain and delivers up to 32.5 dBm of output power.

The device is sold in a RoHS compliant miniature 3 x 3 x 0.8 mm 16-pin QFN package to make automated assembly simple. Its small and thin package size makes the device an ideal solution for radios built in small form

factors for mobile applications.
