Engineering
After thorough analysis, our experienced RF Engineers with their advanced simulation skills and tools provide optimal and feasible design proposals as well as the most efficient performance estimations. Recently, the power handling expectations for our systems have notably increased; MIRAD has accrued profound expertise via extensive R&D studies of reliable feasibility analysis for high power applications. Testing and validation is an indispensable element of development for new RF solutions; our testing capabilities and infrastructure are also available for third party systems. Based on the comprehensive experience gained with earth station applications, our engineering team is also in a position to deliver on-board applications.
- System Design
- RF Simulation & Reflector Design
- High Power Applications
- Testing & Validation
MIRAD Engineering Design Process
The design of our high quality systems and components is complex. It requires a profound RF engineering experience acquired during a considerable amount of time working with MIRAD on similar projects.
Take a look at the MIRAD engineering design process below.
Whether you have questions regarding antenna sizes, mechanical antenna stability requirements, or reflector compliance with specific frequency bands, our engineers are happy to provide detailed and precise answers.
We Provide:
- Antenna geometries for the main- and sub-reflector for new ground stations including reflector deformation analysis
- Antenna performance simulations (e.g. antenna efficiency, radiation pattern, G/T calculations)
- Definition of the key antenna parameters of existing antennas as a starting point for the feed system design
- Feasibility assessment of antenna upgrades
(e.g. change of frequency bands) - Beam waveguide calculation for large ground stations
High transmission power can create several effects that might distort the RF signals. Our engineers recently concluded in-depth multiphysics analysis and simulation of implications of high power applications of the complete RF path.
For the design of high power feed systems and feed networks, a special focus is required for the analysis of the following physical effects:
- Heat dissipation / cooling concepts
- Risks for voltage breakdown
As a result from this analysis, we are able to deliver reliable high power solutions up to 60 kW or even 100 kW (currently in testing phase) for Deep Space Antennas.
In our in-house anechoic chamber (8m x 6m x 6m), MIRAD tests the antenna characteristics of our own systems and prototypes, as well as third party RF products up to 70 GHz. (contact us to check availability and for a quote). Our measurements are three dimensional and in high resolution. The test procedures are software defined for synchronic VNA and hardware-motion controlling.
Our well equipped inventory of measurement tools (for RF and mechanical validation) allows for the execution of any necessary test procedure, and documenting that our deliverables meet – or in many cases – are even better than the agreed upon specifications.
Factory Acceptance Tests are done via telephone or our testing & validation expertise can be witnessed in person.

The selection of the correct termination is extremely important to avoid overheating and is driven by the actual power level of your system. Our sales team is more than happy to support you to define the suitable component.
Air Inlet
The MIRAD microwave air inlets are available for all common waveguide sizes and all common flange standards. The air inlets are the indispensible component in every waveguide system and can be combined with an connector defined by the user.
Pressure Window
MIRAD has designed a series of pressure windows optimized for the use in common earth stations where a low overpressure of almost 50 mbar protects the waveguide system against moisture and dirt. Only highest quality grade of materials are used to manufacture each individual pressure window and to maintain the high performance of your entire system. They are available for all common waveguide sizes and flange standards.
Feed Window / Radome
In order to prevent moisture and dirt from entering the feed system, the feed horn aperture is closed with a feed window. Depending on the diameter of the aperture, the frequency and the internal overpressure, different materials have to be used. MIRAD can provide you either with a customized pre-cut of your feed window according to your sketch or with sheets of Kapton™, CoreTex™ or Sefar tissue. Do not hesitate to contact us.

Factory Acceptance Tests are done via telephone or our testing & validation expertise can be witnessed in person.
Components
- Feed Combiner
- Waveguides
- Filter
- Coupler
- Terminations
- Other
Our standard feed combiners often can be found as one key part of our feed systems. Should you consider outsourcing the adaption or upgrade of your feed system entirely, MIRAD is the perfect partner. With our antenna upgrade experience you will get a technically and financially optimized system. However, the feed combiners are also available as stand-alone units for different frequency bands.
Feed Combiner Components
- Blue: Taper, interface to the circular waveguide
- Green: Orthomode transducer (OMT), separation of polarization
- Orange: Diplexers, separation of transmit and receive frequency bands
- Turquoise: Hybrid couplers, recombination of orthogonal signals to produce circularity
Any component of the feed combiner is available as single component as well. However, in order to get best possible performance a single source solution is recommended.

Whether your specifications are sketched or ready for production is of minor importance. We undertake any necessary design-work, conducted in close cooperation with you and will then manufacture in accordance with our renowned excellent Swiss precision standards. It goes without saying that we deliver any shape, from the simple, straight single component to the highly complex forms of waveguide runs.
MIRAD is proud to have fulfilled every customers technical specifications with precisely designed and manufactured filters, and we strive to continue to do so.
We carry a wide range of standardized products: waveguide and coaxial filters for all typical transmit, receive and harmonic reject filter applications in all RF bands. Furthermore, MIRAD has years of experience in the development and production of filters for channel combination.
Key Features
- Precise and accurate material simulation
- Customized combinations of filter-topology for best performance
- Very low insertion loss
- Best return loss
- High stop-band attenuation
In development and production, MIRAD sets high standards through the use of the CNC-machined waveguide structures in split block technique. Our team of highly specialized development engineers, supported by the latest software tools, are keen to challenge your specifications with an elegant and efficient solution that will guarantee electrically and thermally stable filter systems for your daily, uninterrupted use. Do not hesitate, contact us with your specification, however unusual it may be.
Our wide variety of couplers covers all typical specifications. These high performance products range from simple directional couplers and power splitters/combiners to tailor-made components to meet your individual requirements.
Key Features
- Exact coupling values
- High directivity
- Optimized design in line with your application
- High precision couplers available
In the development of our standard products, our focus was specifically on the best price-performance ratio. If these couplers do not satisfy your requirements, we are capable of customizing a high quality coupler by combining any necessary coupling value with the best frequency linearity, directivity and return loss in a wide frequency range.
Our wide variety of high grade terminations applicable for small, medium and high power handling as well as high precision measurements, have been developed to enable best possible price-performance ratio for your individual application. The power range of our terminations starts from below 1 W up to 4 kW and above.
Key Features
- Models with and without forced cooling available
- High precision terminations for calibration and measurement
- Excellent return loss
- Power handling up to 4 kW and above
- M&C interfaces
- Control interface compatible to industry standard
The MIRAD microwave high power terminations are designed to terminate waveguides with a very good return loss within the complete range of waveguide bands. With the integration of the correct termination, the risk of injury through hot surfaces is eliminated. The terminations are pressure tight and outdoor proof. The selection of the correct termination is extremely important to avoid overheating and is driven by the actual power level of your system. Our sales team is more than happy to support you to define the suitable component.
Air Inlet
The MIRAD microwave air inlets are available for all common waveguide sizes and all common flange standards. The air inlets are the indispensible component in every waveguide system and can be combined with an connector defined by the user.
Pressure Window
MIRAD has designed a series of pressure windows optimized for the use in common earth stations where a low overpressure of almost 50 mbar protects the waveguide system against moisture and dirt. Only highest quality grade of materials are used to manufacture each individual pressure window and to maintain the high performance of your entire system. They are available for all common waveguide sizes and flange standards.
Feed Window / Radome
In order to prevent moisture and dirt from entering the feed system, the feed horn aperture is closed with a feed window. Depending on the diameter of the aperture, the frequency and the internal overpressure, different materials have to be used. MIRAD can provide you either with a customized pre-cut of your feed window according to your sketch or with sheets of Kapton™, CoreTex™ or Sefar tissue. Do not hesitate to contact us.
