RF Circulator Tutorial

RF circulators are devices with three RF ports that allow users to control the direction of signal flow in a RF circuit. These devices allow both RF receivers and transmitters to connect to a single RF antenna. The "circular" nature of the device causes the signal from the transmitter to go to the antenna, and the signal from the antenna to go directly to the receiver without interference from the third device.

Instructions

    • 1

      Connect one end of your first coaxial cable to your RF transmitter. Connect the other end of this cable to the "1" port on your RF circulator.

    • 2

      Connect one end of your second coaxial cable to your RF antenna. Connect the other end of this cable to the "2" port on your RF circulator.

    • 3

      Connect one end of your third coaxial cable to your RF receiver device. Connect the other end of this cable to the "3" port on your RF circulator. Your three devices are now properly hooked up to the circulator.
