RF Generators

Radio Frequency Generators RFG50
Fully Customized Radio Frequency Generators (50 W, up to 10 MHz)

Jump to: Options Download Additional Information

The radio frequency generators RFG50 are manufactured according to the customer's specifications. Each device is individually calibrated for the capacitance of the load and the cables, the attainable amplitude varies accordingly. The mechanical design and the electrical wiring are adjusted to the specific requirements as well.

The frequency of the output voltage is fixed according to the customer's specifications. The amplitude of the output voltage is controlled by an external DC supply.

These devices are the third generation of our RF generators, a further development of the original design published in Rev. Sci. Instrum. (see below). The generators are controlled by an FPGA and can be equipped with a precise amplitude measurement (option A) or a remote control (option R) enabling detailed monitoring of the operating parameters.

A special interface (Device-Link) can be used to connect the generator to an adjustable power supply unit or an ion detector to synchronize them in mass-selective systems.

Options

If desired, we will calculate the operating parameters required for your trap or ion guide. Simply contact us with the necessary details your multipole type and dimensions, the mass range of the ions or particles, as well as their transverse kinetic temperature / energy.
