KCT8578HT

5GHz 802.11be Front-End Module

Introduction

KCT8578HT is a highly integrated RF front-end integrated circuit incorporates key RF functionality needed for IEEE 802.11a/n/ac/ax/be WLAN systems operating in the 5.15-5.925GHz range. It integrates a high-efficiency, high-linearity power amplifier (PA) + T/R switch + low noise amplifier (LNA) with dual gain steps and with LNA-Bypass, the associated matching network and harmonic filters all in one device.

 

KCT8578HT 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 directional RF coupler are integrated to support closed-loop power control within the system.

 

KCT8578HT is assembled in a compact, low-profile 3x5x0.812mm 24-lead LGA package, which is an ideal RF front-end solution for implementing 5GHz high-power WLAN systems supporting multiple standards including 802.11a/n/ac/ax/be.
