ABSTRACT:
An isolator for ultra-high frequencies provides a broadband characteristic by simulating a carved-out copper block with stacked copper laminates. Internal structures are formed by photolithographic processing of the copper sheets. Ferrite elements and a unilateralizing resistor are captivated within the stack of sheets which provides inductance, capacitance and optimal ground return paths, as well as heat sinking for the resistor. No external matching network or tuning is required.
