5GHz Mid Power 802.11ax RF Front-end Module

KCT8546Q

5GHz Mid Power 802.11ax RF Front-end Module

Introduction

KCT8546Q 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. KCT8546Q integrates a high-efficiency, high-linearity power amplifier (PA), a low noise amplifier (LNA) with bypass, the associated matching network, and harmonic filters all in one device.

KCT8546Q has simple and low-voltage control logic, and requires minimal external components. A power detector is also integrated for accurate monitoring of output power from the PA.

KCT8546Q is assembled in a compact, low-profile 2.5x2.5x0.55mm 16-lead QFN package. KCT8546Q is the ideal RF front-end solution for implementing 5GHz high-power WLAN systems supporting multiple standards including 802.11a/n/ac/ax.
