【Introduction】

KCT8577SN is a highly integrated RF front-end integrated circuit incorporates key RF functionality needed for IEEE 802.11a/n/ac/ax/be WLAN systems operating in the 5.15-5.85GHz range. It integrates a high-efficiency, linearizable power amplifier (PA), a low noise amplifier (LNA) with bypass, a double pole double throw (DPDT) switch, the associated matching network, and harmonic filters all in one device.

KCT8577SN provides an excellent heat dissipation environment for 802.11be network equipment which has multiple RF paths configuration. It achieves ultralow power consumption while providing a competitive EVM level when cooperates with the DPD algorithm. In addition, a DC voltage output power detector and a directional RF coupler are integrated to support closed-loop power control within the system.

KCT8577SN is assembled in a compact, low-profile 3x3x0.57mm 16-pin MIS package. It is the perfect RF front-end solution for implementing 5GHz high performance WLAN systems supporting multiple standards.
