SPDT & SP3T

Introducing ACST Schottky-based SPDT & SP3T RF Switches, for ultimate accuracy of Spaceborne RF instruments with precise calibration enablement

ACST’s Schottky–based SPDT & SP3T RF switches play a critical role in space calibration systems by connecting the receiver to different signal sources, such as the antenna & reference loads, to enable continuous calibration to compensate for receiver gain variations, temperature drift, & component aging, ensuring measurement accuracy throughout the mission lifetime.

What makes ACST’s Schottky-based SPDT & SP3T RF switches stand out?

• Low Insertion loss : <1.5 dB at 160–170 GHz
• High Isolation : >30 dB
• Ultra- : Tens of nanoseconds
• No mechanical moving parts for enhanced reliability
• Lowest DC power consumption
• Compact and lightweight design
• High linearity and excellent power handling capability

These performance characteristics make ACST Schottky-based SPDT & SP3T RF switches ideally suited for demanding space, aerospace, & high-frequency instrumentation applications, where reliability, precision, & long-term stability are essential. As RF & sub-THz technologies continue to advance, look for more innovative solid-state switching solutions from ACST will strive to build blocks for next-generation space missions
