KCT KCT8539SD-1

KCT8539SD-1 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 - 5.85GHz range. KCT8539SD-1 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. KCT8539SD-1 has simple and low - voltage control logic, and requires minimal external components. A power detector is also integrated for accurately T monitoring of output power from the PA. KCT8539SD-1 is assembled in a compact, low - profile 3×3×0.75mm 16 - lead QFN package. KCT8539SD-1 is the ideal RF front - end solution for implementing 5GHz high - power WLAN systems supporting multiple standards including 802.11a/n/ac/ax.
