High peak and high average radiofrequency power transmit/receive switch for thermal magnetic resonance

To study the role of temperature in biological systems, diagnostic contrasts and thermal therapies, RF pulses for MR spin excitation can be deliberately used to apply a thermal stimulus. This application requires dedicated transmit/receive (Tx/Rx) switches that support high peak powers for MRI and high average powers for RF heating. To meet this goal, we propose a high‐performance Tx/Rx switch based on positive‐intrinsic‐negative diodes and quarter‐wavelength (λ/4) stubs.
