KCT8253C
【Introduction】
KCT8253C is a fully integrated 802.11b/g/n/ac 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 T/R switch all in one device. The antenna port can be switched between Transmit mode, Receive mode and Bluetooth mode.
KCT8253C is a 3.3V supply voltage power amplifier that conserves power consumption while remain a high linear output power and excellent throughput. A DC voltage output power detector is integrated to support closed-loop power control within the system.
KCT8253C is assembled in a compact, low-profile 2.3x2.3x0.55mm 16-pin QFN package. This is an ideal RF Front-End solution for implementing 2.4GHz high performance WLAN systems supporting multiple standards.
