KCT8270HE

2.4GHz 802.11ax RF Front-End Module

Introduction

KCT8270HE 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.

 

KCT8270HE is a 5V&3.3V supply voltage power amplifier that conserves power consumption while remain the highest linear output power and excellent throughput. A DC voltage output power detector and a directional RF coupler are integrated to accurately monitor the output power of the PA.

 

KCT8270HE is assembled in a compact, low-profile 3×3×0.76mm 16-pin LGA package. It is the perfect RF front-end solution for implementing 2.4GHz high-performance WLAN systems supporting multiple standards.
