Abstract :
An invariant for lossless reciprocal 4-port circuits with reflection symmetry is derived. It is shown that all these circuits can be transformed by external compensation into ideal 4-port circuits with perfect matching and isolation. The transmission coefficient and isolation ports are uniquely determined by the invariant. Furthermore, a design method for the external compensating circuits is described
