In industrial systems, the source and microwave chamber are often separated. Waveguides are ideal for sending high-power microwaves. Losses in waveguides are small and connections are durable and tight. For the construction of waveguide lines, we recommend sections of straight waveguides of varying lengths, a series of angular waveguides and additional elements such as an isolator or a tuner.
Waveguide elements are connected by flanges. In stationary waveguide lines, the flanges are bolted together. For users who often change the configuration of waveguides, MARKOM has developed a method of connecting flanges with eccentric clamps.
WR340SW straight waveguides
The WR340SW series includes straight (rigid) waveguides with a length of approx. 0,25; 0,5; 1,0 and 1,5m, in accordance with the WR340 standard.
At the ends of each waveguide there are flanges, to choose from: bolted or joined with eccentric clamps (the connection method developed by MARKOM). Flanges allow connecting waveguides with a microwave generator, other waveguides or radiators in any configurations.
Waveguides and flanges are made of aluminum. The whole thing is laser welded and then powder coated or glass blasted.
WR340AW angular waveguides
Waveguides from the WR340AW series allow you to change the direction of the microwaves in the E or H plane by an angle of 30, 45 or 90o.
At the ends of each waveguide there are flanges, to choose from: bolted or joined with eccentric clamps (the connection method developed by MARKOM). Flanges allow connecting waveguides with a microwave generator, other waveguides or radiators in any systems and configurations.
Waveguides and flanges are made of aluminum. The whole thing is laser welded and then powder coated or glass blasted.

BJ2211 launcher
Launcher is a short section of the waveguide with magnetron attachment points. This solution is most often used in industrial devices and systems, where the microwave energy from the magnetron is fed directly into the working chamber.
BJ-2211 launcher works with most magnetrons up to 1,5 kW. The mounting flange allows you to screw the launcher to the jacket of the chamber with M6 screws. Placing an additional cover will protect the waveguide from contamination.
WR340 launcher
Launcher is a short section of the waveguide with magnetron attachment points. This solution is most often used in industrial devices and systems, where the microwave energy from the magnetron is fed directly into the working chamber.
WR340 launcher works with most magnetrons up to 2 kW. The spacing of the magnetron mounting holes is 35x114,3 and 47,6x114,3mm. The mounting flange allows you to screw the launcher to the jacket of the chamber with M6 screws.
It is made of aluminum. The whole thing is laser welded and then glassed.
Radiator
Radiator is a universal type of horn antenna, whose task is to focus and direct the microwave beam to a selected area. The dimensions of the radiator provide optimal working conditions for most jobs that use microwave technology.
Equipped with a microwave flange, it is attached to the generator or waveguide with 10 screws. The radiator is made entirely of laser-welded aluminum and powder coated.
Waveguide pressure window
The task of the window is to transfer microwave energy between two areas of different pressure or environment.
It ensures the tightness of vacuum or high pressure structures. It separates gases and vapors from the environment.
It is used in plasma systems, vacuum drying, high pressure heating, and the chemical sector.
It is characterized by a low reflection coefficient, resistance to high temperature, and work with high microwave power.

Isolator
The isolator is part of the waveguide line. Its task is to protect the magnetron against the negative effects of the reflected wave.
Waveguides and flanges comply with the WR340 standard. With a low loss factor, it offers a high degree of insulation.
The water cooling system ensures high efficiency and the ability to isolate the reflected wave with high microwave power.
