Developing modern high frequency circuits requires a high level of precision, efficiency and reliability. Even in the early stages of development, numerous factors must be considered to avoid costly design changes, additional prototypes and unnecessary development effort later in the project.
Modern simulation tools such as Microwave Office make it possible to analyze and optimize high frequency circuits long before manufacturing begins. Design centering and yield analysis help evaluate how robust a design is against component tolerances and manufacturing variations. This allows critical parameters to be identified early and significantly improves the overall reliability of the system.
A key foundation is provided by manufacturer specific libraries containing linear and nonlinear component models. These enable realistic simulations and create a reliable basis for the development of demanding high frequency circuits.
Electromagnetic simulation also plays an increasingly important role. Within Microwave Office, critical PCB sections or individual structures can be modelled as 2.5D or 3D electromagnetic simulations and are seamlessly integrated into the overall circuit simulation. This makes it possible to account for parasitic effects, coupling and losses far more accurately than with circuit simulation alone.
Existing development data can also be reused efficiently used further. PCB layouts can be imported directly from ODB++, IPC-2581 or Gerber files, while measured data such as Touchstone files can be incorporated into the simulation. Comparing simulation results with real measurement data enables continuous verification and optimization throughout the development process.
Another major advantage of modern development environments is the ability to compare design alternatives at an early stage. Different design approaches can be evaluated objectively before manufacturing begins, allowing performance, manufacturability and cost to be assessed side by side. This provides a solid basis for fact based decisions while significantly reducing development risks.
Simulation driven high frequency circuit development shortens development cycles, improves design quality and provides the foundation for high performance and reliable RF systems.
