摘要：
A low impedance transceiver circuit consisting of a transmit-receive switch circuit, a class-D amplifier and a transimpedance amplifier (TIA) was newly designed and tested for a nitrogen-14 NQR. An NQR signal at 1.37 MHz from imidazole was successfully observed with the dead time of similar to 85 mu s under the high Q transmission (Q similar to 120) and reception (Q similar to 140). The noise performance of the low impedance TEA with an NQR probe was comparable with a commercial low noise 50 Omega amplifier (voltage input noise: 0.25 nV/root Hz) which was also connected to the probe. The protection voltage for the pre-amplifier using the low impedance transceiver was similar to 10 times smaller than that for the pre-amplifier using a 50 Omega conventional transceiver, which is suitable for NQR remote sensing applications.
