5GHz 802.11ac RF Front-End Module


5GHz 802.11ac RF Front-End Module


KCT8526H is a highly integrated RF front-end integrated circuit incorporates key RF functionality needed for IEEE 802.11a/n/ac WLAN systems operating in the 5.15-5.85GHz range. KCT8526H integrates a high-efficiency, high-linearity power amplifier (PA), a low noise amplifier (LNA) with bypass, the associated matching network, LO rejection, and harmonic filters all in one device.


KCT8526H has simple and low-voltage control logic, and requires minimal external components. A power detector is also integrated for accurate monitoring of output power from the PA.


KCT8526H is assembled in a compact, low-profile 3.0x3.0x0.55mm 16-lead QFN package. KCT8526H is the ideal RF front-end solution for implementing 5GHz high-power WLAN systems supporting multiple standards including 802.11a/n/ac.
