The RF-100 is a 100W RF power amplifier for use with magnetic resonance imaging and nuclear magnetic resonance systems. This 100W-class, AB push-pull linear MRI RF power amplifier covers the 100 kHz to 30 MHz frequency range. The 100W peak power is within the 1-20 MHz range. When this MRI RF power amplifier is used with the “Research Lab” MRI from Pure Devices, the 90° pulse widths are < 5 µsec, which is useful for the investigation of solid samples and the single-point imaging of solids.
The RF-100 is also suitable for MRI, NMR and other scientific applications.
