High-frequency RF Generator

High-frequency RF Generator /
High-efficiency Pulse RF Generator

13.56MHz 1kW/3kW/5kW (pulse)

The durability of NRF’s high-efficiency high-frequency generators [NR1NP], [NR3NP] and [NR5NP] has dramatically improved with our original high reliability power amplifier compared to the conventional high-efficiency RF generators.

The high-efficiency amplifier’s weakness was its low resistance to reflective power. NRF’s high-efficiency RF generators possess durability for reflective power as high as 600W or greater to output of 3kW, and can endure sudden change in loads during short circuit and opening.

NRF is confident in recommending this generator also equipped with various protective circuits.
