Expert Millimeter-Wave Engineering Consulting Services

The Millimeter-Wave spectrum covers the 30 GHz to 300 GHz bandwidth, and these frequencies have been historically reserved for radio astronomers, secure communications, military applications, and government applications. However, the worldwide need for additional frequency assignments for products has seen large portions of the Millimeter-Wave Spectrum recently taken for commercial applications. The introduction of 5G technology continues to expand into the Millimeter-Wave spectrum. The applications for frequency assignments within the Millimeter-Wave spectrum are limited only by the ingenuity of inventors and engineers to develop equipment for use at these frequencies. SiberSci, LLC is experienced working across the Millimeter-Wave spectrum, so call us today to assist with your project.

SiberSci, LLC is a Millimeter-Wave Consultant which provides Millimeter-Wave Consulting services for a wide range of circuit topologies. SiberSci, LLC provides services for the theoretical and numerical analysis, design, development, fabrication, testing, validation, and optimization of:

  • transmission lines (microstrip, stripline, coplanar waveguide, coax, rectangular waveguide, cylindrical waveguide, elliptic waveguide,…),
  • filters (lowpass, bandpass, highpass, band reject,…),
  • resonators (coaxial, cylindrical, rectangular, clam-shell, dielectric,…),
  • delay lines,
  • phase shifters,
  • couplers,
  • impedance-matching circuits,
  • dielectric lenses,
  • Signal Integrity (SI) analysis,
  • GaN and GaAs power amplifiers, low-noise amplifiers (LNAs), and application-specific amplifiers,
    1. 1Load-Pull Optimization of amplifier active device performance.
  • Temperature stabilized GUNN diode oscillators, and
  • Millimeter-Wave dielectric characterization of temperature-dependent complex permittivity and permeability of plasmas, powders, liquids, and solids, and systems analysis.

Our experience allows SiberSci, LLC to review both your performance specifications and size constraints for the defined Millimeter-Wave hardware, from which SiberSci, LLC can make recommendations for one or more hardware configurations to satisfy the stated requirements. SiberSci, LLC can also review proprietary performance specifications, size constraints, and client proposed hardware configurations to determine if these concepts are suitable for the intended application, or determine if the design concept must be modified to satisfy the stated requirements. Performance and physical limitations for each design concept will be documented during the review process, and modifications to each design concept will be documented to illustrate how the design concepts must be adapted to satisfy the performance and size limitations. If some portion of the performance or size specification is found to be physically impossible to achieve, then these problem areas are revealed along with recommendations to circumvent these barriers to achieving the requisite performance.

SiberSci, LLC is experienced using Ansys HFSS as part of the Ansys Electronics Workbench, CST Microwave Studio, Comsol, FEKO, SONNET Software, and Keysight ADS and Genesys to support the Computational ElectroMagnetics (CEM) aspects of these programs. Clients can specify the use of one or more of these CEM tools for their project as long as the client provides a valid license for using the code, or pays for contract access to the code of choice. If the client is unable to select the appropriate CEM code for their project, then SiberSci, LLC is prepared to assist each client with selecting the appropriate CEM code(s) to ensure the success of their project.

It is important for each client to realize that the accuracy of CEM simulations are dependent upon the frequency and temperature-dependent material properties (thermal conductivity, complex permittivity, relative permittivity, loss tangent, electrical conductivity, density, specific heat,…) of the metals and dielectrics used for fabricating their circuits, so these material properties must be measured so they can be included in the CEM simulations. Laboratory and contract resources are available to determine these material properties, which are essential for providing accurate CEM simulations of circuits and systems. SiberSci, LLC can provide each client with the capability to only use valid material properties for their CEM simulations.

Let’s Start Work On Your Project

Starting work on your important project is relatively simple, so please submit your inquiry for a Millimeter-Wave Consulting project to Dr. Scott Best, and specifically state if a Non-Disclosure Agreement (NDA) is required to protect your business-sensitive information, Intellectual Property (IP) or Proprietary Data (PD). SiberSci, LLC will provide an NDA for review, negotiation, and amendment by the client to safeguard and protect their IP and PD. SiberSci, LLC will also provide a budgetary quotation and schedule for performing the client-defined Millimeter-Wave Consulting effort after reviewing the performance and size requirements. Work on the Millimeter-Wave Consulting project commences when a contract has been negotiated and legally executed by SiberSci, LLC and the client.


SiberSci, LLC is built upon the professional experience of Dr. Scott Best, who has worked in both industry and government. His professional experience has witnessed dramatic changes in techniques available for solving Electromagnetic Engineering problems, as well as for performing laboratory measurements and experiments.
