5GHz High Efficiency 802.11ax RF Front-end Module


5GHz High Efficiency 802.11ax RF Front-end Module


KCT8546QL 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 5.15-5.95GHz range. KCT8546QL integrates a high-efficiency, high-linearity power amplifier (PA), a low noise amplifier (LNA) with bypass, the associated matching network, LO rejection, and harmonic filters all in one device. 

KCT8546QL has simple and low-voltage control logic, and requires minimal external components. A power detector is also integrated for accurately monitoring of output power from the PA.

KCT8546QL is assembled in a compact, low-profile 2.5x2.5x0.55mm 16-lead QFN package. KCT8546QL is the ideal RF front-end solution for implementing 5GHz high-power WLAN systems supporting multiple standards including 802.11a/n/ac/ax.
