KCT2821L

1.0 ~ 3.0 GHz low insertion loss SPDT RF Switch

Introduction

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.
