KCT8234D

2.4GHz 802.11ac RF Front-End Module

Introduction

KCT8234D is a fully integrated 802.11b/g/n/ac 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.

 

KCT8234D is assembled in a compact, low-profile 2.5*2.5*0.4mm 16-pin QFN package. It is the perfect RF Front-end solution for implementing 2.4GHz high-performance WLAN systems supporting multiple standards.
