KCT2821L

1.0 ~ 3.0 GHz 低插損 SPDT 射頻開關

產品介紹

KCT2821L 是一款單刀雙擲 (SPDT) 開關，其工作頻率范圍為 1.0~3.0GHz。用于 WLAN 應用中的模式切換。 KCT2821L 使用先進的開關技術，為所有開關路徑保持低插入損耗和高隔離度。

該開關實現的高線性度性能和低插入損耗使其成為低功率發射/接收切換應用的理想選擇。 根據施加到控制引腳 (VC) 的邏輯電壓，RFC 引腳使用低插入損耗路徑連接到兩個開關射頻輸出（RF1 或 RF2）之一，而 RFC 引腳和另一個（RF2 或 RF1）之間的路徑引腳處于隔離狀態。 

該開關采用緊湊的 1.25 × 2.1 × 0.95 mm、6 引腳 SOT-363 封裝。

KCT2821L具有低插入損耗、高隔離度、低功耗等特點，是一款用于IEEE 802.11b/g/n/ac WLAN 系統理想的射頻開關解決方案。

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.
