WELCOME TO OUR COMPANY’S WEBSITE

MWTC is a good choice to solve your electrical problems.

Our company has extensive experience in solving problems related to antennas, radio frequency equipment, electromagnetic compatibility, design of electronic equipment, inspection of electrical equipment or installations and educational activities. We apply ourselves wherever solutions cannot be copied from the net or obtained as an AI product, but need to be developed from the ground up, engineered verified and put into practice.

Data processing

We are able to process noisy data from measurements of e.g. directional characteristics of antennas in such a way that the characteristic graph is highlighted with minimal loss of information. We use advanced mathematical methods and freely available mathematical software for processing.

Moving average

Smoothing noise by successive averaging of multiple data samples to preserve the character of the waveform and minimize noise.

Fourier analysis

Signal processing via Fourier series followed by analysis of higher order coefficients.

Wave transformation

Curve (data) approximation via wavelet transform.

RF equipment design

We have experience in design of RF measuring devices (SA with position and measured data recording), adapting cells (AM transmitters 25 kW and 5 kW, voltage up to approx. 8 kV), (set of antennas on PCB for GPS, GSM, LTE reception), antennas (adaptation and reception of 2.4 GHz WiFi), filters (microstrip) and classical electronic devices (consumer electronics).

Analytical calculation

In the case of design matching (impedance matching, filters, antennas, stip lines, coaxial lines, …) it is necessary to find the initial solution through analytical calculation.

Numerical modelling

Refinement of the analytical calculation for a specific task.

Perimeter design

Printed circuit boards, components, path elements, wiring, attenuation, amplification, MW elements.

Production

Sparrow’s nest, PCB, FR4, Teflon, rogers, aluminum, copper, silver, topology, connectors, connections.

Measurement

S_{11},\; S_{22},\; S_{12},\;S_{21}, directional characteristic, input impedance, antenna factor, gain.

Implementation

Impacts of imperfections, environmental effects, power supply problems, reference problems, high and low frequency buffer currents.

Measurement in the RF region

We are the only ones in Slovakia who can measure directional characteristics of large antenna arrays. We have experience with measuring about 8 FM arrays with outputs up to 200 kW. We can evaluate the measured data and compare them with the telecommunication authority permits. We can plot the directional characteristics of a large antenna system in both horizontal and vertical planes. We can allocate possible antenna damage in the system.

Quadcopter

Finding the exact location of the antenna mast and mission planning, promotional flight, horizontal and vertical flights.

Measuring device

Connection of the measuring device so that it is neither awakened nor stimulated by the transmitting signal, time and space synchronization.

Let

Franhofer zone, Fressnel zone, EMC problems, mooring lines, control and attitude measurement accuracy problems .

Data processing

Application of noise suppression methods. Problems of maxima and minima in the measured directional characteristic. Incorrect data. GPS.

Application of permits

Plotting of the intensities allowed by the telecommunications authority in the measured characteristics. Drawing conclusions.

Measuring protocol

Create a measurement protocol that includes data, curves, conclusions and recommendations.

Revision of electrical equipment

MWTC, s.r.o. does not only deal with high frequency technology. In our work we often encounter requests for inspections of electrical equipment or installations. The company has a number of knowledgeable §24 personnel who can carry out this work. According to the decree Ministry of Agriculture and Rural Development of the Slovak Republic No 508/2009 All electrical equipment, including installations, is subject to periodic inspection. The period depends on the type of building and external influences.
