Wi-Fi 6E 3.3V 802.11ax RF Front-end Module


Wi-Fi 6E 3.3V 802.11ax RF Front-end Module


KCT8773HE 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 - 7.1GHz range. KCT8773HE 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. 

KCT8773HE has simple and low-voltage control logic, and requires simplified external components. A DC voltage output power detector and a directional RF coupler are integrated for further improve the linearity of the PA.

KCT8773HE is assembled in a compact, low-profile 3x3x0.55mm 16-lead MIS package. It is the ideal RF front-end solution for implementing WIFI 6E highpower WLAN systems supporting multiple standards including 802.11a/n/ac/ax.
