5GHz 802.11ax RF Front-End Module

KCT8539SD-1

5GHz 802.11ax RF Front-End Module

Introduction

KCT8539SD-1 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. KCT8539SD-1 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.

 

KCT8539SD-1 has simple and low-voltage control logic and requires minimal external components. A power detector is also integrated to accurately monitor the output power of the PA.

 

KCT8539SD-1 is assembled in a compact, low-profile 3x3x0.75mm 16-lead QFN package. KCT8539SD-1 is the ideal RF front-end solution for implementing 5GHz high-power WLAN systems supporting multiple standards including 802.11a/n/ac/ax.
