Waveguide Components: Isolator

An isolator, which is a circulator plus a dummy load, is often employed directly after the power source in order to protect the magnetron from excessive levels of reflected power. Power reflected back to the magnetron can cause overheating and moding. This can result in reduced efficiency and shortened tube life. The use of an isolator is a good safety precaution to take and becomes increasingly important as the power levels increase. For power levels between 2 and 6 kW, an isolator is recommended. For power levels of 6 kW and above, an isolator should be considered a requirement.
