A coupling matrix technique is presented for the synthesis of nonreciprocallossless two-port networks. This technique introduces complex inverters tobuild the nonreciprocal transversal network corresponding to the nonreciprocalcoupling matrix. It subsequently transforms this matrix into canonicaltopologies through complex similarity transformations. The complex inverters inthe final topology are transformed into real inverters and gyrators forimplementation simplicity. A second-order example is then given to illustratethe proposed technique. Possible implementations of the gyrators involved inthe final design are also discussed.
