KCT8536C

KCT8536C PRELIMINARY DATASHEET 5GHz WLAN 802.11ac RFIC WITH PA, LNA AND SPDT TX PA_EN Description PA KCT8536C 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. KCT8536C 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. ANT VDET LNA RX KCT8536C 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. KCT8536C is assembled in a compact, low-profile 2.0x2.0x0.75mm 12-lead LGA package. KCT8536C is the ideal RF front-end solution for implementing 5GHz high-power WLAN systems supporting multiple standards including 802.11a/n/ac.

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.
