KCT8539SE

5GHz 802.11ax RF Front-End Module

Introduction

KCT8539SE is a highly integrated RF Front-End Integrated Circuit incorporates key RF functionality needed for IEEE 802.11a/n/ac/ax WLAN systems operating in the 5.15-5.85GHz range. It integrates a high-efficiency high-linearity power amplifier (PA), a low noise amplifier (LNA) with bypass, the associated matching network, and harmonic filters all in one device.

 

KCT8539SE has simple and low-voltage control logic, and requires minimal external components. A voltage power detector is also integrated for accurately monitoring of output power from the PA.

 

KCT8539SE is assembled in a compact, low-profile 3x3x0.75mm 16-lead QFN package. It is the ideal RF front-end solution for implementing 5GHz high-power WLAN systems supporting multiple standards including 802.11a/n/ac/ax.
