【Introduction】

KCT8523D is a highly integrated RF Front-End Integrated Circuit incorporates key RF functionality needed for IEEE 802.11a/n/ac WLAN systems operating in the 5.15-5.85GHz range. KCT8523D 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.

KCT8523D has simple and low-voltage control logic, and requires minimal external components. Power detector is also integrated for accurately monitoring of output power from the PA.

KCT8523D is assembled in a compact, low-profile 3x3x0.55mm 16-lead QFN package. KCT8523D is the ideal RF front-end solution for implementing 5GHz high-power WLAN systems supporting multiple standards including 802.11a/n/ac.
