【Introduction】

KCT8585HE 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. It integrates a high-efficiency, linear power amplifier (PA), a low noise amplifier (LNA) with bypass, the associated matching network, and harmonic filters all in one device.

The LNA and PA disable functions of KCT8585HE ensure low leakage current while switched off. A power detector is also integrated to provide close-loop power control within the system.

KCT8585HE is assembled in a compact, low-profile 3x3x0.57mm 16-lead MIS 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.
