KCT8522C PRODUCT DATASHEET 5GHz High-Power WLAN 802.11ac RFIC WITH PA, LNA AND SPDT LNA_EN RX_EN GND ANT 16 15 14 13 Description NC 1 12 GND RX 2 11 VCC NC 3 10 VCC VDD 4 9 5 6 7 8 DET TX_EN GND TX NC KCT8522C 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. KCT8522C 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. KCT8522C 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. KCT8522C is assembled in a compact, low-profile 3x3x0.55mm 16-lead QFN package. KCT8522C is the ideal RF front-end solution for implementing 5GHz high-power WLAN systems supporting multiple standards including 802.11a/n/ac.
