A Design of 10-100 MHz Broadband NMR Transmission-line Probe

This work demonstrated a broadband NMR probe with a bandwidth of 10-100 MHz. Based on transmission-line structure, broadband transmission was achieved. As for broadband reception, high-speed active T/R switches and low-noise differential amplifiers were used for high-sensitivity RF reception. The SNR of FID signal detected by broadband probe was 74% of that of conventional resonance probe, which means the feasibility of the broadband NMR transmission-line probe was verified.
