KCT8570SN

5GHz High-efficiency DPD FEM Solution

Introduction

KCT8570SN 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, non-linear power amplifier (PA), a low noise amplifier (LNA) with bypass, the associated matching network, and harmonic filters all in one device.

 

KCT8570SN provides an excellent heat dissipation environment for 802.11be

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. In addition, a DC voltage output power detector and a directional RF coupler are integrated to support closed-loop power control within the system.

 

KCT8570SN is assembled in a compact, low-profile 3x3x0.75mm 16-pin QFN package. It is the perfect RF front-end solution for implementing 5GHz high performance WLAN systems supporting multiple standards.
