KCT2821L

1.0 ~ 3.0 GHz 低插损 SPDT 射频开关

产品介绍

KCT2821L 是一款单刀双掷 (SPDT) 开关,其工作频率范围为 1.0~3.0GHz。用于 WLAN 应用中的模式切换。 KCT2821L 使用先进的开关技术,为所有开关路径保持低插入损耗和高隔离度。

该开关实现的高线性度性能和低插入损耗使其成为低功率发射/接收切换应用的理想选择。 根据施加到控制引脚 (VC) 的逻辑电压,RFC 引脚使用低插入损耗路径连接到两个开关射频输出(RF1 或 RF2)之一,而 RFC 引脚和另一个(RF2 或 RF1)之间的路径引脚处于隔离状态。 

该开关采用紧凑的 1.25 × 2.1 × 0.95 mm、6 引脚 SOT-363 封装。

KCT2821L具有低插入损耗、高隔离度、低功耗等特点,是一款用于IEEE 802.11b/g/n/ac WLAN 系统理想的射频开关解决方案。


KCT2821L is a single-pole, double-throw (SPDT) switch intended for mode switching in WLAN applications. Using advanced switching technologies, the KCT2821L maintains low insertion loss and high isolation for all switching paths.

The high-linearity performance and low insertion loss achieved by the switch make it an ideal choice for low-power transmit/receive applications. Depending on the logic voltage applied to the control pin (VC), the RFC pin is connected to one of the two switched RF outputs (RF1 or RF2) using a low insertion loss path, while the path between the RFC pin and the other (RF2 or RF1) pin is in a high-isolation state. 

The switch is manufactured in a compact, 1.25 × 2.1 × 0.95 mm, 6-pin SOT-363 package.

KCT2821L has the characteristics of low insertion loss, high isolation, and low power consumption. It is an ideal RF switch solution for IEEE 802.11b/g/n/ac WLAN systems.
