5GHz High Power 802.11ax RF Front-end Module
KCT8548HE 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. It 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.
A power detector is integrated on KCT8548HE for accurately monitoring of output power from the PA. KCT8548HE is a 5V supply voltage power amplifier that conserves power consumption while maintaining the highest linear output power and excellent throughput. The PA power detector and a digital enable control are also integrated. A coupler function is integrated to further improve the linearity of the FEM.
KCT8548HE is assembled in a compact, low-profile 3 x 5 x 0.75mm 24-lead QFN package, which is an ideal RF front-end solution for implementing 5GHz high-power WLAN systems supporting multiple standards including 802.11a/n/ac/ax.
