RF Engineering has evolved and matured since wireless communication began in 1901 with the first RF transmitter and receiver assemblies demonstrated by Marconi. RF Engineering applications expanded over the past century, with new applications introduced daily.

Historical applications such as police and firefighter radios work in the RF spectrum as well as broadcast AM, FM, and Television stations. Applications also include Ham Radio operators, linear accelerators for particle physics, garage door openers, and communication systems for aircraft and submarines. Another application includes RF Energy for processing a large percentage of food products, which is addressed in the RF Heating discussion. Regardless, RF systems are still an essential part of our lives in the 21st century. Therefore, if you are working on a new piece of equipment, or are having performance issues with an existing RF system, contact SiberSci, LLC for engineering assistance.

Therefore, as you can see, SiberSci, LLC is an RF Engineering Consulting service providing RF Design Consulting, RF Engineering, and RF Consulting resources for a wide range of power levels and 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,…),
• lumped filters (lowpass, bandpass, highpass, band reject,…),
• resonators (coaxial, cylindrical, rectangular, clam-shell, LC,…),
• delay lines,
• phase shifters,
• couplers,
• impedance-matching circuits,
• Software Defined Radios, RF Front-End, and Beam Forming Networks,
• Signal Integrity (SI) analysis, and
• systems analysis.

Our RF Engineering experience allows us to review client performance specifications and size constraints for new RF hardware. The review allows SiberSci, LLC to make recommendations for one or more hardware configurations to satisfy these requirements. SiberSci, LLC can also review proprietary performance specifications, size constraints, and client-proposed hardware configurations to determine if these concepts suit the intended application. The review permits us to determine if design changes are needed to satisfy the stated requirements.

Furthermore, performance and physical limitations for each design concept are documented during the review process. This review permits modifications to the design concept to be explored to illustrate how each design concept must be adapted to satisfy the performance requirements and size limitations. Suppose some portion of the performance or size specification is found to be physically impossible to achieve. In that case, these problem areas are discussed with recommendations to circumvent these barriers to achieving the requisite performance criterion.

RF Engineering Computational ElectroMagnetics (CEM)

Next, SiberSci, LLC is experienced using Ansys HFSS as part of the Ansys Electronics Workbench, CST Microwave Studio, FEKO, Comsol, SONNET Software, and Keysight ADS and Genesys to support the Computational ElectroMagnetics (CEM) aspects of every RF Engineering program. Clients can specify using 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 cannot 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.

The accuracy of CEM simulations for RF circuits is directly dependent upon the frequency and temperature-dependent properties of the materials used for building each circuit. For the metals and dielectrics, these frequency and temperature-dependent material properties (thermal conductivity, complex permittivity, loss tangent, electrical conductivity, density, specific heat,…) must be used to accurately simulate the circuits.

Finally, material properties must be accurately measured to 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 provides each client with the capability to only use valid material properties for their CEM simulations.
