摘要：

A probe with a high-frequency amplifier of a continuous-wave Q-meter-type electron paramagnetic resonance (EPR) spectrometer operating at 300 MHz is described. The probe is inductively connected with both an exciting high-frequency generator and the amplifier. The amplifier is matched to the probe for obtaining a minimum noise figure of 2.9 dB. The single-scan EPR line with a 1.7-G width and 3 × 1018 resonant paramagnetic centers is recorded with a signal-to-noise ratio of about 260.
