Use the Best RF Design Software for High Frequency PCBs

Designing radio frequency systems to support high frequencies and digital interfaces is challenging and requires the best RF design software tools. RF engineering in a high GHz band takes the best RF design software to ensure accurate PCB trace routing, layer stack design, and circuit design. Use Altium Designer for your RF design process and to take your next GHz band system to manufacturing.

ALTIUM DESIGNER

A unified PCB design software application with circuit design features, a powerful PCB editor, and simulation features for RF engineering professionals.

Many electronics engineers are familiar with digital design concepts, but what about the peculiarities of RF design? The field is sometimes called "black magic" and for good reason, as so much of the discipline requires studying and understanding electromagnetism at a deep level. For the RF designer, they need a particular set of design features that can help them model their systems as well as transfer designs into a PCB layout. They also need full control over their design documentation to ensure their designs will be manufactured to specification.

Designers that use the best RF design software can perform a variety of system level simulations at the circuit level, as well as build a PCB layout for their new device. A platform like Altium Designer gives users total control over their RF designs through simulation tools inside the schematic, post-layout simulations for crosstalk and reflection simulation, a layer stack manager for building a circuit board, and integrations with other design tools. When you need to design an RF PCB to support systems operating at any frequency, from GHz bands to mmWave, use a comprehensive design platform like Altium Designer, the industry’s best digital, RF, and mixed-signal design software.

Accurate System Design and Simulation in RF Engineering

Every new electronic system will start as a circuit design, and electronics engineers need powerful design and simulation tools to build and qualify RF systems. The best RF circuit design software should provide a set of simulation tools for circuit simulation that go beyond the generic components found in typical SPICE simulation applications.

• An integrated SPICE simulation engine
• Import simulation models extracted from other programs
• Matching circuit design with access to real components
• Footprint creation for printed components and assignment to components in component libraries

As an example, consider a standard printed devices like a Wilkinson divider or a coupler. These devices can be represented in a schematic in your PCB design software as a multi-port schematic symbol. In an external field solver program (such as CST, Ansys, Simbeor, etc.), it's possible to extract the equivalent SPICE subcircuit model for these devices. These equivalent SPICE models can then be saved in a standard model format (MixedSim, LTSpice, PSpice, etc.). After saving a model, the symbol and footprint for the printed component can be designed, and the simulation can be attached to the component in a schematic sheet.

Any of these components that have a model attached can be used in a SPICE simulation to evaluate system functionality.

Altium Designer gives you access to both sets of verification tools to help ensure your physical layout matches the functionality you expect from your system design.

Post-Layout Simulations and 3rd-Party Electromagnetic Field Solvers

After you complete the PCB layout of your RF design, it’s important to put the design through a round of simulations to ensure any RF signal integrity problems are solved or prevented. Altium Designer includes a set of post-layout simulation tools that can be used to reflection and crosstalk analysis, as well as impulse response analysis by designing a short input pulse in the stimulus tool. The simulation tool in Altium Designer operates inside the PCB Editor on a net-by-net basis to help you speed up design verification before prototyping.
