Description
KCT8227B 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 single-pole, double-throw (SPDT) switch all
in one device.
The PA power detector and a digital enable control are also integrated.
KCT8227B is assembled in a compact, low-profile 2.5*2.5*0.5mm 16-pin QFN
package. It is the perfect RF Front-end solution for implementing 2.4GHz high
performance WLAN systems supporting multiple standards.
