100 W Radiofrequency Amplifier

RF 100 radiofrequency amplifier

The RF-100 is a 100 W class AB push-pull linear RF power amplifier covering the 100 kHz to 30 MHz frequency range.  The 100 W peak power is within the 1-20 MHz range.  When the RF-100 is used with the Research Lab MRI, the 90° pulse widths are < 5 µsec, useful for investigation of solid samples and single point imaging of solids.

The RF-100 is also suitable for MRI, NMR and other scientific applications.
