KCT8871HE

5G & 6GHz 802.11ax RF Front-End Module

Introduction

KCT8871HE is a highly integrated RF Front-End Integrated Circuit incorporates key RF functionality needed for IEEE 802.11a/n/ac/ax/be WLAN systems operating in the 5.1-7.2GHz range. KCT8871HE integrates a high-linearity power amplifier (PA), a low noise amplifier (LNA) with bypass, the associated matching network and harmonic filters all in one device.

 

KCT8871HE is a 3.3V supply voltage power amplifier that conserves power consumption while maintaining the highest linear output power and excellent throughput. A DC voltage output power detector and a directional RF coupler are integrated to support closed-loop power control within the system.

 

KCT8871HE is assembled in a compact, low-profile 3x3x0.75mm 16-lead QFN package. KCT8871HE is the ideal RF front-end solution for implementing 5~7GHz ultra-wide band high-power WLAN systems supporting multiple standards including Wi-Fi 7.
