What is a Circulator

The circulator is a three-port non-reciprocal device that transmits RF signals in a unidirectional sequence. Signals entering port 1 are transmitted to port 2, signals entering port 2 are transmitted to port 3, and signals entering port 3 are transmitted to port 1, with minimal loss in the forward direction and high isolation in the reverse direction. Circulators are primarily employed to separate transmit and receive signals in radar and communication systems, to protect sensitive receivers from high-power transmitter outputs, and to route signals between multiple ports with minimal interference. An ideal circulator provides lossless transmission in the forward direction while directing reflected or unwanted signals to a termination port, improving system efficiency and protecting critical components.

Why RFecho

RFecho designs and manufactures RF and microwave circulators in micro strip, SMD, coaxial, cryogenic, and drop-in series for a variety of applications. These products provide very low insertion loss, excellent isolation across temperature and power, and solutions with a very wide frequency spectrum. From concept to final product manufacture and testing, comprehensive internal abilities have been built. These high-performance components are highly compact, weather resistant, and have been tested in the worst circumstances encountered at sea, air, land, or space. Our commitment to technical advancement, combined with expertise in ferrite and dielectric materials, guarantees that our products are always at the cutting edge of microwave technology.
