초록

We designed and manufactured 300MHz NMR RF Transceiver. NMR system is composed of NMR Spectrometer, Superconductive Magnet and Pulse Programmer, GUI. NMR RF Transceiver is composed of transmitter, receiver, frequency synthesizer. T/R switch, main power amp., RF coil. To phase modulation, transmitter is composed of mixer, splitter and combiner et al. To weak signal detection, receiver is composed of pre-amp., filter, mixer et al. Each module is manufactured PCB. And installed NMR system to detect chemical component of specimen. In result, we can get the information of specimen.
