KCT8570HE

5GHz Mid-High Power 802.11ax RF Front-end Module

Introduction

KCT8570HE 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, LO rejection, and harmonic filters all in one device.


 A power detector is integrated on KCT8570HE for accurate monitoring of output power from the PA. KCT8570HE is a 5V supply voltage power amplifier that conserves power consumption while maintaining the highest linear output power and excellent throughput. A coupler function is integrated to further improve the linearity of the FEM.


KCT8570HE is assembled in a compact, low-profile 3 x 3 x 0.75mm 16-lead QFN package, which is an ideal RF front-end solution for implementing 5GHz high-power WLAN systems supporting multiple standards including 802.11a/n/ac/ax.
