KCT4222L

2.4GHz 低噪声放大器开关模组

产品介绍

KCT4222L 是一种射频集成前端模块 (FEM)，它在一个芯片内集成了带旁路的低噪声放大器 (LNA) 和单刀双掷 (SPDT) 开关。 KCT4222L 具有低噪声系数 (NF) 和简单的控制逻辑。 

KCT4222L 工作电压为 3.3V 并只消耗非常低的电流。 在传输模式下，当设备处于非活动状态时芯片可以彻底关闭进一步节省电量。

KCT4222L 采用紧凑、扁平的 2.3x2.3x0.55mm 16 引脚 QFN 封装。 KCT4222L 是实现 2.4GHz 高功率 WLAN 系统的理想射频前端解决方案，支持多种标准，包括 802.11b/g/n/ac。

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. 

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.
