Using AI-Optimized Tuning To Design 5G And mmWave Filters

The demand for 5G applications increases the need for radio frequency (RF) and microwave filter components in the mm-Wave frequency bands.

“5G applications present some unique challenges to mm-Wave and 5G passive components,” said Diamond Liu, product manager of SynMatrix. “Fabrication capability limitations make it very difficult for designers to produce components that are manufactured easily. Some of the major obstacles include the extra cost for pre-sampling and time-consuming tuning and debug activities.”

Despite the design challenges to produce these products, there are options for Ansys HFSS users to overcome them. SynMatrix, an Ansys software partner, offers a RF and microwave design platform for 5G and mm-Wave components. It also supports a complete line of structures including cavity, waveguide, coaxial, low temperature co-fired ceramic (LTCC) chip, ceramic and microstrips.

Liu added, “With SynMatrix’s comprehensive design platform, designers can accurately produce the required RF performance and simulation. This is faster, easier and cost-effective.”

Structures supported by SynMatrix

HFSS users can import their design parameters into SynMatrix which enables them to leverage a comprehensive set of tools that accelerate the design process.

After importing the data, users can utilize the platform to auto-tune and edit the parameters necessary to meet the desired RF design output. The simplified workflow and toolset helps them estimate and fine-tune the design long before a physical prototype is built.

Edit HFSS parameters directly within the SynMatrix interface (left). HFSS design variables automatically import into SynMatrix (middle). Once the simulation is complete, the corresponding S2P file will be imported into the system (right).

Review the optimization process over each iteration, and observe the dimension change versus the coupling coefficient changes (left). The convergence of the result is also plotted over each simulation iteration cycle (right).

The SynMatrix design platform offers a list of comprehensive tools that include:

• Coupling matrix synthesis
• Dispersive effect control
• Matrix optimization and Monte-Carlo analysis
• Peak power handling

From a simulation point of view, users will benefit from:

• Computer-aided tuning and diagnostic features
• Advanced coupling matrix extraction
• Multiport tuning and deep optimization

One of the most exciting features available for HFSS users is SynMatrix’s AI-optimized tuning function. Thanks to this tool, users will benefit from:

• An AI-optimized system that converges to a solution automatically
• Advanced space mapping and tuning error features
• An integrated HFSS workflow with progress monitoring features

There are a number of RF and microwave filter design tool alternatives, but few are as comprehensive as the design workflow offered with SynMatrix and HFSS.
