Choosing RF Switches for High-Power Applications (.PDF Download)

Oct. 23, 2020

Switching is crucial in many radio-frequency (RF) applications, whether it’s changing signal pathways through test equipment on a lab bench, or rapidly disconnecting a radar antenna from a transmitter and connecting it to a receiver, and then quickly switching back. As such, it’s important for users to select the correct type of switch for their high-power RF applications.

In a high-power application, the RF signal power can range from a few watts to tens of thousands of watts. Such applications may include switching between multiple antennas, bringing an amplifier online, or connecting to a backup piece of equipment.
