【Introduction】

KCT4521L is an integrated Front-End module (FEM) which is designed for IEEE 802.11a/n/ac/ax WLAN systems operating in the 5.15-5.85GHz range. KCT4521L integrates a low noise amplifier (LNA) with bypass, and single-pole double-throw (SPDT) switch in one device.

KCT4521L is assembled in a compact, low-profile 2.3x2.3x0.5mm 16-pin QFN package. KCT4521L is the ideal RF front-end solution for implementing 5GHz highpower WLAN systems supporting multiple standards including 802.11a/n/ac/ax.
