KCT8574HE

5GHz 3.3V 802.11ax RF Front-end Module

Introduction

KCT8574HE is a highly integrated RF front-end integrated circuit incorporates key RF functionality needed for IEEE 802.11a/n/ac/ax WLAN systems operating in the 5.15-5.95GHz range. KCT8574HE integrates a high-efficiency, high-linearity power amplifier (PA), a low noise amplifier (LNA) with bypass, the associated matching network, LO rejection, and harmonic filters all in one device. 


KCT8574HE has simple and low-voltage control logic, and requires minimal external components. A power detector is also integrated for accurately monitoring of output power from the PA.


KCT8574HE is assembled in a compact, low-profile 2.5x2.5x0.55mm 16-lead QFN package. KCT8574HE is the ideal RF front-end solution for implementing 5GHz high-power WLAN systems supporting multiple standards including 802.11a/n/ac/ax.
