KCT8553C
5GHz 802.11ac RF Front-End Module
Introduction
KCT8553C 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. KCT8553C 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.
KCT8553C 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.
KCT8553C is assembled in a compact, low-profile 2.3x2.3x0.55mm 16-lead QFN package. KCT8553C is the ideal RF front-end solution for implementing 5GHz WLAN systems supporting multiple standards including 802.11a/n/ac.
