2.4GHz 802.11ac RF Front-End Module


2.4GHz 802.11ac RF Front-End Module


KCT8232H 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. The PA power detector and a digital enable control for transmitter power ramp on/off control is also integrated.


KCT8232H is assembled in a compact, low-profile 3×5×0.75mm 24-pin QFN package. It is the perfect RF Front-end solution for implementing 2.4GHz high-performance WLAN systems supporting multiple standards.
