Abstract : The patent relates to an edge-guided mode microstrip device having a pair of input ports and a common output port, with two separate ferrite substrates each having a microstrip conductor electrically connected between a respective input port and the common output port. Both microstrip conductors additionally each have a conductive or inner edge spanned by a resistive film which acts as a resistive load. The other or outside conductive edge of each of the conductors includes an exponentially tapered segment which when a predetermined biasing magnetic field is applied transversely relative to the field of the substrates, causes input microwave energy at the two input ports to travel along the respective exponentially tapered edges and combine at the common output port. Any reflective energy returning from the output port will travel along the inner edges and be absorbed in the resistive load.
