KCT8246HE

2.4GHz 802.11ax RF Front-End Module

Introduction

KCT8246HE is a fully integrated 802.11b/g/n/ac/ax WLAN RF front-end module (FEM) which incorporates key RF functionality. It is integrated with a high-efficiency power amplifier (PA), a low noise amplifier (LNA) with bypass, the associated matching network and a single-pole, double-throw (SPDT) switch all in one device.

 

The PA power detector and a digital enable control are also integrated.

 

KCT8246HE is assembled in a compact, low-profile 3*3*0.55mm 16-pin QFN package. It is the perfect RF front-end solution for implementing 2.4GHz high-performance WLAN systems supporting multiple standards.
