Cenfire’s Switch Platform

The CF2140 integrates four low-loss, fully symmetric high-voltage SPST switches with a flexible serial or parallel control interface. These switches offer industry leading capability combining wide bandwidth with DC offset voltage support, small area and low height, and zero leakage current, making them ideal for multiplexing source and measurement units as well as routing high-speed digital signals. Additionally, the high 120 V tolerance enables new applications such as RF filter tuning. The switches are normally open when off or even unpowered and cannot self-actuate.
