Nonlinearity 2.4GHz Wi-Fi 6 FEM


KCT8270N is a fully integrated 802.11b/g/n/ac/ax 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.

KCT8270N is a 5V supply voltage power amplifier that conserves power consumption while remain the highest linear output power and excellent throughput. The PA power detector and a digital enable control are also integrated. A coupler function is integrated to further improve the linearity of the FEM.

KCT8270N is assembled in a compact, low-profile 3*3*0.76mm 16-pin LGA package. It is the perfect RF front-end solution for implementing 2.4GHz high performance WLAN systems supporting multiple standards.
