RF, Plasma and Radiation Technology

Gas discharges, radiation technology and high-frequency engineering.  We serve with practical experience from kHz to several GHz.  Apart from the classical application "wireless information technology" the RF application "wireless energy supply" gains more and more importance. Examples of smaller and larger projects from this range of topics:

RF  Electronic

Transmitter and receiver for 4 MHz ultrasound signals.  By frequency mixing of the amplified signal with the original carrier a frequency shifted Doppler signal is obtained. Here the blood flow close to the human heart in the aorta.

RF Plasma Display
	Advertising panel with RF energy supply. The individual bulbs and LEDs are mounted contact- and wireless inside the panel. For the first time multiple plasma bulbs and LED are fed from a single RF energy source.

Elektrode-less Bulbs
	Elektrode-less mercury high pressure bulbs: The power and power density is up to 5 times increased with respect to an ordinary arc lamp.

Fiberoptic RF-Field Probe
	Fiberoptic RF-Field Probe for up to 5 GHz.

Drying with Microwave
	Aluminumcase with 1,6 kW RF supply at 2,45 GHz for mobile drying of ground samples.

Plasma Coating of Phosphor Materials
	Thin ceramic coatings of phosphor materials can be deposited by this pyrolitic coating setup. The Europium- or Terbium-based phosphors show red and greenish fluorescence. In contrast to common phosphor deposits (e.g. inside fluorescence bulbs) these ceramic films are much more rigid and stable.

Rare Earth doped glasses and fibers
	Europium and Terbium doped glasses and fibers show red and green fluorescence as well.

Flexible RF wave-guide
	Flexible RF waveguide for 2,45 GHz and high power transmission. Adapter for ordinary 800 W - magnetrons.
