How to Design 5G and mm-Wave Filters Using AI-Optimized Tuning

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.
