Abstract
A single-pole, double-throw, transmit/receive switch for switching a NMR coil between a transmit mode and a receive mode comprises two diode bridge switches on opposites sides of a node the is common with the two diode bridges and the NMR coil. One of the two diode bridges is positioned between the coil and a preamplifier for signals received from the coil, and the other diode bridge is positioned between the coil and a RF signal transmitter for connecting and disconnecting transmitted signals to and from the coil. The NMR coil is connected to the switches through a resonant impedance matching network.
