SEREN RF-Generators, HR-Series

The Seren HR-2001 is a third-generation, 2000 Watt RF Generator. It may be purchased at 13.56 MHz, 27.12 or 40.68 MHz. This lightweight, watercooled ½ rack unit is designed to exceed the most stringent vacuum processing demands. The HR-2001 can be used as the sole source for plasma generation, as a Bias generator, or as one of several generators in a multiple generator configuration. Front panel indicators include AC ON, RF On, Alarm and Interlock. An optional Remote controller (front panel controls and indicators) may be purchased.

Seren “HR Series” products incorporate a separate surface mount technology printed circuit board for controls and RF amplifier. The RF amplifier is powered by a switch-mode power supply.

Seren “HR Series” products utilize LDMOS Field-Effect Transistors in the power amplifier stages. The unit operates in a class AB mode providing power accuracy and stability across the entire power range.
