KCT8278SN
【Introduction】KCT8278SN is a fully integrated 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, a single-pole, double-throw (SPDT) transmit/receive (T/R) switch and the associated matching network all in one device.
KCT8278SN provides an excellent heat dissipation environment for 802.11be network equipment which have multiple RF paths configuration. It achieves ultra-low power consumption while providing a competitive EVM level when cooperates with the DPD algorithm. In addition, a DC voltage output power detector and a directional RF coupler are integrated to support closed-loop power control within the system.
KCT8278SN 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.
