S-TEAM was founded in 1990 by a group of scientists from the Slovak University of Technology in Bratislava. The company initially specialized in the research and development of advanced microwave measurement techniques, software, and automated systems. Today activities are focused on high power microwave instrumentation used in many applications such as heating, drying, curing, vulcanization and plasma generation for chemical vapor deposition proceses or plasma etching used in semiconductor manufacturing processes. Our product range includes microwave instruments specifically designed for the 900 MHz, 2.45 GHz and 5.8 ISM bands. The company’s current flagship product is the HOMER (HOt MEasuRement) series of autotuners, which function as high-power vector reflectometers and automatic impedance matching systems. The more complex HOMER systems are complemented by a range of smaller components, including diode detectors, standard power meters, directional couplers, both directional and bidirectional detectors, and bidirectional power meters, all specifically designed for high-power microwave processing installations. S-TEAM is also engaged in consulting across multiple areas of high-power microwaves and in the design and development of specialty equipment tailored to customer requests. This includes simple components such as power splitters, transitions between different transmission lines, waveguide windows, as well as more complex systems like applicators for heating, sintering, sterilization and plasma. S-TEAM proudly serves markets all over the world including European Union, USA, Japan, China, Australia, Korea, Israel, Brazil and many other countries. The company is still managed by a group of scientist and we consider our highly qualified and experienced staff (scientists & engineers), precise work and in-house R&D as our main strengths and our main competitive advantage.

  • HOMER Autotuner ISM 2450 MHz, WR340 Waveguide

  • The HOMER-Series STHT 2.45-GHz Autotuner integrates the HOMER Analyzer (automatic impedance and power measurement system) and HOMER Mototuner (a three-stub motorized tuner) in one compact unit. Based on the WR340 (R26) waveguide, the system works under the full-power operating conditions of magnetron-based microwave generators. The Analyzer part measures both the magnitude and phase of reflection coefficient as well as the incident, reflected and absorbed power, and frequency. The Mototuner consists of three stepping-motor-driven tuning stubs spaced in mutual distances of nominally one quarter of guide wavelength. The Tuner uses data measured by Analyzer for fast automatic impedance matching of time-varying loads in all industrial applications, including plasma. The system is designed for CW, high-ripple (Rectified) and Pulsed sampling modes. Also available is matching for non-zero reflection coefficient magnitude (defined mismatch tuning). The peak working power is set at the manufacture time as specified in the customer’s order.

    STHT can be:

    • Used autonomously without an external controller.
    • Controlled from a personal computer or another controller via RS232, RS422, CAN, or Ethernet/IP interface,
    • Integrated into a LabVIEW environment.

    Configuration Options:

    • Cooling: Air-cooled or water-cooled. The main purpose of water cooling is isolating the internal electronics from dusty or hot-air environment.
    • Waveguide Transitions: Basic Units can be provided with precision transitions to other transmission line types, such as WR430, WR284, 7-16 DIN, 7/8'' EIA, attached at one or both ends, allowing their easy integration in installations with different transmission media.
    • The high-speed motors versions can decrease tuning time compared with standard versions.

    HomSoft Windows Control, Visualization and Data Logging Software

    Although HOMER can operate as a stand-alone system, the HomSoft control, visualization and data logging software (Fig. 2) significantly expands its capabilities. The basic features include:

    • Microsoft Windows® environment.
    • Accurate measurement of complex reflection coefficient and its displaying in various formats.
    • Measurement of incident, reflected, and absorbed powers and their displaying in various formats.
    • Numerical readout of signal frequency, load reflection coefficient and power in various formats.
    • Periodic data logging of all measured quantities.
    • Graphical interface for tuner control (manual stub movement, step-by-step/continuous autotuning).
    • Prescribed scenario of tuning stub movements enables, among others, automated Rieke diagram measurement.
    • Extensive on-line help.

  • BPM112 is a bidirectional power meter designed for accurate simultaneous measurement of incident and reflected powers up to 30 kW in high-power 2450 MHz industrial applications using an WR340 (R26) rectangular waveguide. Each power meter is calibrated individually.

    The BPM integrates a four-port directional coupler with the following components in each of its two channels:

    • Zero-bias Schottky diode detector
    • Low noise amplifier
    • 16-bit A/D converter for sampling detector voltages
    • 12-bit D/A converter providing the analog output
    • Microcontroller unit (MCU)
    • Optional display (common for both channels)

    The MCU:

    • Controls both A/D and D/A conversions.
    • Performs detector nonlinearity and temperature dependence correction.
    • Generates the following simultaneous outputs:
    • Two analog outputs, one (FWD) corresponding to the forward (incident) power; one (RFL) to the reflected power.
    • One digital output (RS232, RS422, or CAN Bus).

    The two analog outputs can be:

    • voltage output 0 – 10 V; or
    • current output 4 – 20 mA.

    The desired output type can be switched by the user. Both FWD and RFL outputs are of the same type. The output voltages/currents are linear functions of the microwave powers propagating in the forward and reverse directions of the parent waveguide. The digital outputs provide also internal power sensors temperatures. The RS232 and RS422 outputs have the form of easily readable text streams.

    Configuration Options:

    • LCD Display: An LCD display that shows the incident (FWD) and reflected (RFL) powers as well as the internal power sensors temperatures. The powers are displayed both numerically and by bar indicators.
    • Precision Waveguide: A calibrated assembly consisting of a BPM fixed to a precisely machined parent waveguide with a standard (WR340) or customized length.
    • BPM Cable: An extension cable, branching the DC power supply inputs VDC and GND to the power supply and TX, RX, GND pins to standard D9 RS232 connector.

    BPM Monitor

    The BPM is accompanied by the simple LabVIEW-based Windows visualization application BPM Monitor.

    BPM Monitor is a program for monitoring and controlling BPM devices. It displays graphs of the incident, reflected and absorbed powers as functions of time. The reflection coefficient magnitude is also displayed in a separate graph. The history of the graphs can be extended to up to 24 hours. All data on graphs can be easily exported to Excel for analysis.

    The BPM Monitor also contains a simple RS232 Terminal dialog for setting the internal BPM parameters.

    One can perform a more detailed analysis of the generator output waveform with the help of Samples Waveform and FFT Dialog windows, that show the output power as a function of time and its power spectrum, respectively.

    For LabVIEW programmers wishing to develop their own applications, there is a BPM library of virtual instruments available. The library is a part of the BPM Monitor installation package.
