Microwave Magnetron Heads
Devices, systems, and production lines utilizing microwaves require at least one source of microwave radiation. In industrial applications, MMH series magnetron heads manufactured in Poland by MARKOM are used.
Practical Examples of Magnetron Head Applications
Magnetron microwave heads produced by MARKOM Microwaves operate, among others, in: production lines (drying, heating), chemical industry (process enhancement), food processing (thermal treatment, puffing), research departments (hardening of foundry cores), and scientific institutions (liquid heating).
Design and Technical Specifications
The MMH magnetron heads are compatible with various microwave systems, both in research and industrial applications. They feature a compact design and low weight. All circuits – microwave, power supply, and control – are housed within a single enclosure. Aluminum alloy shields can be anodized or powder-coated, providing corrosion resistance. An efficient cooling system ensures effective heat dissipation.
The microwave output, finished with a mounting flange, complies with one of the international standards – WR340 or WR430. This allows integration of our microwave heads with components from different manufacturers.
Available Microwave Head Variants
The device can operate at an output power of 1000 W or 1500 W, depending on application needs. It offers three cooling system variants: air-cooled, water-cooled, and hybrid – where the power supply is air-cooled and the magnetron is water-cooled. Two operating modes are supported: constant output power or continuous power regulation. Control is possible in two ways: via control voltage adjustment or through an RS485 interface with Modbus RTU protocol. Thanks to the Modbus RTU implementation, integration with SCADA systems and remote monitoring of operating parameters are possible.
Support and Service
MARKOM provides full technical support for MMH magnetron heads, maintaining its own service and warehouse facilities in Poland. Each magnetron head controlled via RS485 comes with a complete Modbus protocol description. MMH heads are configured prior to shipment – once connected to power and cooling, the device is immediately ready for operation.

Switched-mode Magnetron Power Supplies
Magnetrons are used in industrial heating and drying systems, as well as in medical and chemical equipment, plasma technologies and other advanced systems. Their operation requires dedicated power supply systems.
The solution lies in modern impulse power supplies, where PWM technology enables precise control of magnetron output power. The principle of PWM operation is described in more detail in Tech insights.
Power Supplies Rated at 1.0–1.5 kW
The 1.0–1.5 kW power supplies are powered from a single-phase 230 VAC mains. They are intended for use with magnetrons in industrial and medical applications. Where required, they provide output voltage with a low ripple level.
Two cooling options are available. Air-cooled units feature their own ventilation system, effectively protecting internal circuits from overheating.
Water-cooled units require connection to a running water source or a closed-loop cooling system.
Microwave power setting can be configured in three ways. No regulation – the magnetron always operates at full power. 0–5 VDC analog control – the output power is proportional to the control voltage. RS-485 communication – the power is set via the Modbus communication protocol.
The control signal is connected to the interface with I/O sockets.
The magnetron and power supply are linked by high-voltage cables with appropriate connectors.
A wide range of configuration options allows the power supply to be tailored to specific operating conditions and application requirements.
