We suggest a method for mitigating the effects of coil coupling. It is based on a wideband matching technique which can be implemented by a simple circuit modification. The reduced effective reflection will result in less degradation of preamp noise figure in a receive array, and in lower power loss in the transmitter isolators in a parallel transmit system.
