ABSTRACT:
A gated RF preamplifier used in system for performing pulsed RF FT EPR spectroscopy and imaging or MRI. The RF preamplifier does not overload during a transmit cycle so that recovery is very fast to provide for ultra-fast data acquisition in an ultra-fast excitation subsystem. The preamplifier includes multiple low-gain amplification stages with high-speed RF gates inserted between stages that are switched off to prevent each stage from overloading during the transmit cycle.
