A Preamplifier System for Water-Cooled Ultra-High Field NMR Spectrometers
摘要
Abstract
This paper introduces the design and implementation of a preamplifier system for water-cooled ultra-high field NMR spectrometers. The system consists of a controller, a high-band low noise amplifier, a high-band mixer, a broadband low noise amplifier and a broadband mixer. The system was shown to be capable of flexible and fast switching between the transmitter mode and receiver mode, and have low noise figure and large receiving range.关键词
