Wi-Fi 6E High Power 802.11ax RF Front-end Module


Wi-Fi 6E High Power 802.11ax RF Front-end Module


KCT8648HE 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 5.9-6.4GHz range. KCT8648HE integrates a high-linearity power amplifier (PA), a low noise amplifier (LNA) with bypass, the associated matching network, and harmonic filters all in one device. 

KCT8648HE has simple and low-voltage control logic, and requires minimal external components. A DC voltage output power detector and a directional RF coupler are integrated for further improve the linearity of the PA. 

KCT8648HE is assembled in a compact, low-profile 3x5x0.75mm 24-lead QFN package. KCT8648HE is the ideal RF front-end solution for implementing 6GHz high-power WLAN systems supporting multiple standards including 802.11a/n/ac/ax.
