The isolator provides a non-reciprocal microwave transmission path.  That is, microwave energy can travel the transmission path in one direction with little loss but will be greatly absorbed if applied in the opposite direction.  The isolator uses ferrite or garnet material which in the presence of a magnetic field gives this nonreciprocal operation.  The isolator has the third port terminated with a dummy load (termination). As port 1 is the input port, energy reflected from port 2 circulates to the termination where it is dissipated as heat. The isolator consists of two units connected in series to achieve better isolation.
