KCT8278HT
2.4GHz 802.11be RF Front-End Module
Introduction
KCT8278HT is a highly integrated RF Front-End Integrated Circuit incorporates key RF functionality needed for IEEE 802.11a/n/ac/ax/be WLAN systems operating in the 2.4-2.5GHz range. KCT8278HT integrates a high-linearity power amplifier (PA), a low noise amplifier (LNA) with bypass, the associated matching network and harmonic filters all in one device.
KCT8278HT is a 5V supply voltage power amplifier that conserves power consumption while maintaining the highest linear output power and excellent throughput. A DC voltage output power detector and a directional RF coupler are integrated to support closed-loop power control within the system.
KCT8278HT is assembled in a compact, low-profile 3×5×0.812mm 24-pin LGA package. It is the perfect RF Front-end solution for implementing 2.4GHz high performance WLAN systems supporting multiple standards including 802.11a/n/ac/ax/be.
