This work will present the time domain modeling, design, and packaging of a micro miniature 2KW Transmit Receive switch for 7 Tesla proton imaging. It will demonstrate significant advances in packaging and low magnetic susceptibility packaging, all with commercial readily available parts. These miniaturized switches are a critical subsystem circuit needed for high element count TR array at ultra high field and can be mounted directly to the coil and reside within the image field of view.
