An RF switch is also known as a microwave switch and is a device used to route high frequency signals through transmission paths. RF switches (radio frequency) are used extensively in microwave test systems for signal routing between instruments.
Incorporating a switch into a switch matrix system enables you to route signals from multiple instruments to single or multiple DUTs (devices under test). Multiple tests can be performed with the same setup, eliminating the need for frequent connects and disconnects. An RF switch allows for the entire testing process to be automated, increasing the throughput in high-volume production environments.
RF Switch Configurations
• Single pole, double throw (SPDT)
• Multiport switches or single port, multiple throw (SPnT)
• Transfer switches or double pole, double throw (DPDT)
• Bypass switches
Applications
RF switches can be used to route one input to two output paths, allow a single input to three or more output paths or remove a test component from a signal path.
