OTF50RF 300W 13.56MHz RF Generator with Automatic Matching for 50 or 80 mm OD Tube Furnace PECVD Systems
The OTF50RF RF generator is engineered to provide precise radio frequency power for plasma-enhanced chemical vapor deposition (PECVD) processes, including plasma etching, plasma cleaning, and plasma polymerization. It is specifically designed to integrate with tube furnaces having outer diameters of 50 or 80 mm, enabling controlled plasma generation within these systems.
This generator operates at a fixed frequency of 13.56 MHz with a frequency stability of ±0.005%, ensuring consistent plasma excitation. The output power is adjustable from 5 to 300 watts with a tight stability tolerance of ±1%, allowing fine control over plasma intensity. An automatic matching network optimizes impedance matching between the generator and the plasma load, minimizing reflected power and enhancing efficiency.
