1. A dual tuned magnetic resonance medical imaging device for imaging a subject, comprising:
a magnet assembly comprising one dual resonant RF coil or two single resonant RF coils;
a simultaneous dual-tuned T/R switch, the simultaneous dual-tuned T/R switch configured to process a signal with two resonance frequencies from the one dual resonant RF coil or the two single resonant RF coils, simultaneously without tuning,
the simultaneous dual-tuned T/R switch comprising:
a top side and a bottom side of the simultaneous dual-tuned T/R switch, each of the top side and the bottom side includes one microstripline based hybrid coupler, each of the one microstripline based hybrid couplers includes at least one port, and the at least port is connected to a corresponding shunt capacitor configured to tune a resonance frequency;
in a transmission mode, for the simultaneous dual-tuned T/R switch:
the top microstripline based hybrid coupler of the simultaneous dual-tuned T/R switch is activated;
in a receiving mode, for the simultaneous dual-tuned T/R switch:
the top microstripline based hybrid coupler and the bottom microstripline based hybrid coupler of the simultaneous dual-tuned T/R switch are activated.
