A circulator is a device that

A circulator is a ferrite device (ferrite is a class of materials with strange magnetic properties) with usually three ports. The beautiful thing about circulators is that they are non-reciprocal. That is, energy into port 1 predominantly exits port 2, energy into port 2 exits port 3, and energy into port 3 exits port 1 Optical Circulator symbol An optical circulator is a three- or four-port optical device designed such that light entering any port exits from the next. This means that if light enters port 1 it is emitted from port 2, but if some of the emitted light is reflected back to the circulator, it does not come out of port 1 but instead exits from port 3 A circulator is a device that transports radio frequency or microwave signals from one port to another. They typically have three ports. They are made of magnets and ferrite materials with magnetic properties. Circulators can be made to circulate clockwise or counterclockwise

A circulator is a three-port device that has an interesting characteristic. (See Figure 1.) When the RF signal is applied to port 1, it rotates through the device and will exit via port 2. Likewise, any RF signal applied to port 2 will rotate through the device to port three; and an RF signal applied to port 3 will rotate through the device to. 15. A circulator is a device that: a. rotates signal polarity in a waveguide. b. allows a signal to pass in one direction only. c. separates signals among various ports. d. prevents microwaves from being trapped in a waveguid

A circulator pump is a device that is used to circulate water, or coolant, through the piping that leads to radiators, air conditioning units, baseboards, or other convection type items. They help to distribute the coolant, or the heated water, through the home in order to regulate the temperature. Detecting problems with a faulty circulator pump is not a difficult project, but does require.
