Question

The device used in microwave oven to match power between source and load is called circulator. (True/False)

Hint:

A circulator in a microwave oven protects the magnetron by routing reflected power away from it.

Answer 1

True
A circulator is a non-reciprocal passive device used in microwave systems, including microwave ovens, to ensure efficient power transfer. It directs microwave energy from the magnetron (source) to the cavity (load) while preventing any reflected power from damaging the magnetron. It helps in matching impedance between components, ensuring maximum power delivery and protecting sensitive parts from reflected waves.
