2.4GHz 802.11be RF Front-End Module


KCT8280HT is a fully integrated 802.11b/g/n/ac/ax/be WLAN RF Front-End Module (FEM) which incorporates key RF functionality, it is integrated with a high-efficiency power amplifier (PA), a low noise amplifier (LNA) with bypass, the associated matching network and a single-pole, double-throw (SPDT) switch all in one device.


KCT8280HT conserves power consumption while remain 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.


KCT8280HT is assembled in a compact, low-profile 3x3x0.76mm 16-pin LGA package. It is the perfect RF front-end solution for implementing 2.4GHz high performance WLAN systems supporting multiple standards.
