5GHz Mid-High Power 802.11ax RF Front-end Module


5GHz Mid-High Power 802.11ax RF Front-end Module


KCT8575HE 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. KCT8575HE 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. 

KCT8575HE has simple and low-voltage control logic, and requires minimal external components. A power detector is also integrated for accurate monitoring of output power from the PA. 

KCT8575HE is assembled in a compact, low-profile 3x3x0.57mm 16-lead MIS package. KCT8575HE is the ideal RF front-end solution for implementing 5GHz high-power WLAN systems supporting multiple standards including 802.11a/n/ac/ax.
