KCT8870N

5G & 6GHz Dual Band 802.11be FEM

Introduction

KCT8870N 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 an ultra-wide band of 5.1-7.1GHz range. It 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.

KCT8870N provides an excellent heat dissipation environment for Wi-Fi 6 & 7 network equipment which have multiple RF paths configuration. It achieves ultra-low power consumption while providing a competitive EVM level when cooperates with the DPD algorithm. A DC voltage output power detector and a directional RF coupler are integrated to support closed-loop power control within the system.

KCT8870N is assembled in a compact, low-profile 3x3x0.75mm 16-lead QFN package, which is an ideal RF front-end solution for implementing 5~7GHz ultra-wide band high-power WLAN systems supporting multiple standards including Wi-Fi 6 & 7.
