KCT8571HE
5GHz 802.11ax RF Front-End Module
Introduction
KCT8571HE 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 5.15-5.85GHz 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.
KCT8571HE is a 3.3V supply voltage power amplifier that conserves power consumption while maintaining the highest linear output power and excellent throughput. It is integrated with a DC voltage detector and a RF power detector from coupler which are both intended to accurately monitor the output power of PA.
KCT8571HE is assembled in a compact, low-profile 3x3x0.55mm 16-lead QFN 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.
