KCT8239SD

2.4GHz 802.11ax RF Front-End Module

Introduction

KCT8239SD 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.

 

KCT8239SD integrates a DC voltage output power detector, and a digital enable control for transmitter power ramp on/off control.

 

KCT8239SD is assembled in a compact, low-profile 3x3x0.75mm 16-pin QFN package. It is the perfect RF Front-end solution for implementing 2.4GHz high-performance WLAN systems supporting multiple standards.
