RF Switch
This SP8T RF Switch Module (Single Pole Eight Throw) is a compact, high-performance RF switching solution built around the HMC253 integrated circuit. It is designed for applications that require routing a single RF input/output signal to one of eight selectable RF paths with minimal insertion loss and high isolation. The board has SMA female connectors, allowing seamless integration into RF test benches, signal routing systems, antenna selection networks, and automated RF switching environments.
