KCT4222L

2.4GHz Low Noise Amplifier with Switch Module

Introduction

KCT4222L 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. KCT4222L 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.

 

KCT4222L operates at 3.3V and draws low current. In the transmit mode, a shutdown function saves power when the device is inactive.

 

KCT4222L is assembled in a compact, low-profile 2.3x2.3x0.55mm 16-pin QFN package. KCT4222L is the ideal RF front-end solution for implementing 2.4GHz high-power WLAN systems supporting multiple standards including 802.11b/g/n/ac.
