DESIGNS OF RF POWER AMPLIFIERS (HIGH AND LOW Q) AND LUMPED EQUIVALENT CIRCUITS OF TRANSMISSION LINES WITH NMR APPLICATIONS

摘要

A general procedure for designing rf power amplifiers is described. The designs of high Q and low Q, linear, rf power amplifiers at 56. 0 mhz are presented. These amplifiers have been used in double resonance and multiple pulse NMR experiments. Finally, the design of lumped equivalent circuits of transmission lines is discussed. These circuits are shown to possess desirable properties especially in NMR double resonance experiments.
