RF/Microwave Switches

RF/microwave switches are electronic components used to selectively route high-frequency signals between input and output ports. These switches are essential building blocks in radio communication systems, test and measurement equipment, and radar systems. RF/microwave switches are designed to operate in a specific frequency range, and their performance is characterized by parameters such as insertion loss, isolation, and switching speed.

There are different types of RF/microwave switches, including electromechanical switches, PIN diode switches, and solid-state switches. Electromechanical switches use mechanical contacts to switch between input and output ports, while PIN diode switches and solid-state switches use electronic control signals to route signals between different ports. PIN diode switches are suitable for lower power applications, while solid-state switches are capable of handling higher power levels.

RF/microwave switches can be classified based on their configuration and functionality. Single-pole single-throw (SPST) switches have a single input and a single output and can switch between two states, while single-pole double-throw (SPDT) switches have a single input and two outputs and can switch between two output ports. Multi-throw switches have more than two output ports and can switch between multiple states. Switches can also be classified as absorptive or reflective, depending on their ability to absorb or reflect the input signal when it is not being routed to the output port.
