The following technical documentation is authored to provide user application support for the SynMatrix application.

Feature 1: Fine-tune Function

The fine-tune function is a facility tool to allow the user to fine-tune the matrix until all required targets are met. This tuning function can shift the operation frequency up or down while expanding or narrowing the bandwidth by scaling the matrix. Within the tuning process, the designed centre frequency and bandwidth can be kept.

Feature 2: Dispersion Function

“Dispersion” is defined as the a distortion due to the different group velocity versus frequency, especially for non-TEM propagation structure such as waveguide and microstripe or wideband application.

Feature 3: CAT Application

Computer aided tuning was introduced first in the satellite filter industry, and has now been widely adopted to the wireless field. It applies systematic approaches based on either reconstruct filter polynomial, curve fitting or by optimization circuit model to fit and match simulation or measurement responses.

Feature 4: CAT Wideband Application

SynMatrix provides CAT with a proprietary algorithm that has excellent performance in both narrow band and wideband applications.

Feature 5: Power Handling Prediction

SynMatrix offers engineers a simple calculation on power handling prediction. By inputing relevant filter information, the maximum power handling ability can be predicted; meanwhile, based on input data, the user still can judge if the filter can be breakdown or not under the specific input power.

Feature 6: Air Breakdown Prediction

The air breakdown is a physical phenomenon due to ionization which is caused by energetic electrons in a high electrical field. Ionization may make a conducting path, allowing a sharp current to increase.

Feature 7: Stray Coupling Analysis

Stray Coupling is unwanted coupling effects, leaking energy between non-adjacent resonators, which may cause either the unbalanced notch level or extra unwanted transmission zeros.
