SynMatrix Introduction and Overview

How to design RF filters and tune them using an AI optimization system and a real-time tuning workflow.

Welcome!

Greetings engineers, designers, technicians, professors, students and enthusiasts. It is a pleasure and our honour to have the interest of the filter design and engineering community.

SynMatrix is a design and test tuning platform that creates a single user experience across the entire filter design process, from specification design, to test and measurement, and finally, manufacturing and production:



What We Support

The following illustration helps summarize the frequency spectrum SynMatrix supports. As shown, we have support from VHF to the mmWave spectrum and cover a wide variety of vertical industries including 5G, Military Defense, and Aerospace to name a few. SynMatrix is specifically designed for 5G and mmWave requirements, demonstrated by our Dispersive Effect Prediction feature that we will show in future tutorials.


The following displays the type of structures SynMatrix currently support:

Step 1: Specification Analysis

The SynMatrix filter design process begins with specification analysis and filter synthesis, a feature-packed design and analysis platform for complex filter engineering. Some of the features include:

  • Coupling matrix synthesis
  • Dispersive effect analysis
  • Power handling analysis
  • Monte-Carlo analysis
  • Thermal drift analysis
  • ... and much more!

Advanced Coupling Matrix Synthesis

SynMatrix comes with a complete package for coupling matrix synthesis featuring arbitrary topology synthesis, imaginary and complex format transmission zeroes input, and multi-graphics analysis:

Diplexer and Triplexer Support

SynMatrix is also equipped with diplexer and triplexer support, featuring:

  • Arbitrary Topology Synthesis
  • T-Junction and Common Resonator
  • Waveguide T-junction optimization
  • Generic Matrix Optimizer
  • Stored Energy Analysis

Matrix Sensitivity Analysis and Optimization

SynMatrix also includes support for Monte-Carlo analysis and Matrix Optimization for easy and fast set up and convergence for special filter topologies.

Dispersive Effect Control

One of the unique features we offer on SynMatrix is Dispersive Effect Control. We are not currently aware of any other comparing tool that can offer this at the moment. SynMatrix users will be able to predict the RF performance for four types of dispersive effects, and is particularly challenging for wideband applications.

Other Features

  • Peak power analysis
  • Stored energy analysis
  • Thermal drift prediction
  • Coupling matrix editing
  • Marker analysis
  • ... and more to come!

Step 2: Optimization

SynMatrix's second module in the design process is the most defining Optimization system. SynMatrix offers two types of optimizers that are designed specifically for filters:

Advanced Computer-Aided Tuning. A powerful CAT platform that features:

  • Advanced coupling matrix extraction. Two-port coupling matrix extraction, multi-port tuning, and generic circuit-EM optimization
  • Advanced algorithms. Dispersive effect and spurious prediction can be used to extract the error information precisely.

Intelligent Tuning. Smart, flexible optimizers that can be applied to a wide variety of filter applications and structures. Fully integrated with the HFSS workflow. There are two types that users can use for a wide variety of use cases:

  • AI Optimization. One of the world's first AI optimizers featuring automatic runtime processing with Ansys HFSS integration
  • Custom Optimization. Features linear and non-linear optimization modes. Offers step-by-step master control for more experienced designers and more complex design requirements.

Advanced Computer-Aided Tuning

Two-Port Tuning

SynMatrix offers an advanced coupling matrix extraction technique with two-port tuning. Users are able to evaluate the RF performance by extracting error information directly from the simulation or test data (regardless of the lossy or lossless data).

Multi-Port Tuning

SynMatrix also offers the more traditional extraction technique based on Y parameters: Multi-Port Tuning. By defining the lump port in your 3D simulation structure, a user can extract the frequency and coupling information.

Generic Optimization

Based on the circuit model, SynMatrix's generic optimization tool retrieves the EM simulation error by curve-fitting the target through a variety of optimization methods.

Dispersive Effect Control

SynMatrix also has dispersive effect control tools to help manage higher frequency, wideband applications. This feature is useful for planar and coplanar structures, as well as ceramic and ceramic waveguide filters.

Intelligent Tuning

AI Optimization Tuning

The SynMatrix AI Optimization Tuning system is one of the world's first AI-based optimizers available on a commercially-based platform. It combines a reinforced learning system with SynMatrix's proprietary knowledge to help converge to a solution. Results are highly optimized with an efficient training process, fast and accurate with advanced curve-fitting technology, and also features a stabilized control system with anti-crash monitoring.

Advanced Curve-Fitting Algorithm

The advanced curve-fitting algorithm uses advanced polynomial-fitting technology with a smart convergent system that avoids performance oscillation. Smart Training System

SynMatrix is equipped with a smart training system that features a full deviation matrix built with co-coupling effects, which is suitable for complex use cases with quasi-linear coupling performance. The Smart training system intelligently detects key training elements from the user defined topology, which is suitable for CT and CQ topologies.

Ansys HFSS Integration

The SynMatrix AI optimization system has direct integration with the Ansys HFSS workflow. Set up parameters are also fully integrated and users can adjust HFSS variables from the SynMatrix GUI. Once the physical dimensions are mapped, the AI optimization system automatically drives the HFSS simulation and updates the physical parameters in the HFSS 3D model.

Workload Management Tools

SynMatrix also features a number of tools to help manage your workflow including:

  • S2P file storage with simulation process recap
  • Step-by-Step run process overview
  • Dimension and coupling coefficient variation overview
  • System recommends best result

Custom Optimization Tuning

For more complex use cases and added flexibility for more advanced users, SynMatrix offers a custom optimization system with finer and manual controls. Flexible tuning methods are featured which allows users to choose between a linear or non-linear tuning method. Non-linear methods are based on Aggressive Space Mapping (ASM) or the linear slope method. Similar to the AI Optimization tuning workflow, the Custom Optimization system offers one touch HFSS set up and full HFSS control from the SynMatrix GUI.

Step 3: Real-time Tuning

SynMatrix's third module in the design process includes support for a test and measurement workflow which features real-time tuning. Currently we have support for select R&S and Keysight VNA models.

One Button Connection, Plug and Play Set up

Once the user opens the VNA calibration file, all the parameters (start stop frequency, sweep points, etc.) are passed automatically into the SynMatrix GUI. Upon clicking CONNECT, direct communication between SynMatrix and the VNA will be created.

Full VNA control

Once SynMatrix connects with the VNA, the user will be able to fully control the VNA from the SynMatrix GUI interface including: adding traces, adding markers, edit magnitude/phase/VSWR, change the scale, etc.

Streaming and Manual Modes

SynMatrix features two types of modes: streaming and manual mode. Manual mode is used for step-by-step debugging while streaming mode is used for real-time tuning.

Test Report Generation and Export

SynMatrix also enables test report generation and export features.
