The CF2140 4xSPST switch array is based on the CenFire™ low-loss switching technology platform. This highly versatile product supports a wide variety of applications in signal switching and tuning with an emphasis on large-scale matrix switching and high current applications.
The CF2140 4xSPST switch array is based on the CenFire™ low-loss switching technology platform. This highly versatile product supports a wide variety of applications in signal switching and tuning with an emphasis on large-scale matrix switching and high current applications.
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.
