KCT8227D

KCT8227D PRODUCT DATASHEET RX_EN VDET PA_EN 2.4GHz WLAN Front-End Module PA TX Description KCT8227D 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 highefficiency 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. The PA power detector and a digital enable control are also integrated. KCT8227D is assembled in a compact, low-profile 2.5*2.5*0.55mm 16-pin QFN ANT package. It is the perfect RF Front-end solution for implementing 2.4GHz high performance WLAN systems supporting multiple standards.

This device must be protected at all times from ESD when handling or transporting. Static charges may easily produce potentials of several kilovolts on the human body or equipment, which can discharge without detection. Industry-standard ESD handling precautions should be used at all times.
