【Introduction】

KCT8525D-2 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. KCT8525D-2 integrates a high-linearity power amplifier (PA), a low noise amplifier (LNA) with bypass, the associated matching network, and harmonic filters all in one device.

KCT8525D-2 has simple and low-voltage control logic and requires minimal external components. A power detector is also integrated to accurately monitor the output power of the PA.

KCT8525D-2 is assembled in a compact, low-profile 2.5x2.5x0.55mm 16-lead QFN package. KCT8525D-2 is the ideal RF front-end solution for implementing 5GHz high-power WLAN systems supporting multiple standards including 802.11a/n/ac.
