KCT4221L
2.4GHz Low Noise Amplifier with Switch Module
Introduction
KCT4221L is an integrated Front-End module (FEM) which integrates a low noise amplifier (LNA) with bypass, and single-pole double-throw (SPDT) switch in one device. KCT4221L has a low noise figure (NF) and simple control logic. The device has pins in the switch to LNA path which can add custom filtering.
KCT4221L operates at 3.3V and draws low current. In the transmit mode, a shutdown function saves power when the device is inactive.
KCT4221L is assembled in a compact, low-profile 2.3x2.3x0.55mm 16-pin QFN package. KCT4221L is the ideal RF front-end solution for implementing 2.4GHz high-power WLAN systems supporting multiple standards including 802.11b/g/n/ac/ax.
