KCT8670HE

Wi-Fi 6E Mid-High Power 802.11ax RF Front-end Module with CPLR

Introduction

KCT8670HE 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 5.9-6.4GHz range. KCT8670HE 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. 

KCT8670HE is a 5V 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 digital enable control are also integrated. A coupler function is integrated to further improve the linearity of the FEM.

KCT8670HE is assembled in a compact, low-profile 3 x 3 x 0.75mm 16-lead QFN package. KCT8670HE is the ideal RF front-end solution for implementing WIFI 6E high-power WLAN systems supporting multiple standards including 802.11a/n/ac/ax.
