Abstract

A technique for a combined active and passive decoupling circuit in an MRI application is disclosed. The combined decoupling circuit proposes the use of capacitive DC blocking combined with both, active (PIN diode) and passive (cross-diode) switching in a single location. The active and passive switching is combined in a way such that transmit blocking is achieved using a single inductance in parallel with a single coil capacitance.
