  • FilterSolutions® Designs Using Defected Microstrip Structures (DMS)

    Nuhertz Technologies has introduced a feature in its FilterSolutions program to deal with design of filters utilizing Defected Microstrip Structures (DMS). When used with A WR's Microwave Office©, this new modeling capability enables engineers to achieve the accurate synthesis of stripline, microstrip or suspended substrate filter designs in which the use of these resonators proves to be advantageous.

  • A Design Flow for rapid and Accurate Filter Prototyping

    It is the purpose of this application note to outline a robust yet flexible method for the design of lumped element filters using Modelithics Microwave Global Models™, Nuhertz Technologies' FilterSolutions® software, and NI/AWR Design Environment™ software, specifically AXIEM® electromagnetic (EM) simulation. 

  • Accurate High Frequency Lumped Filter Design with Discrete Optimization

    FilterSolutions®, the world leading filter design software created by Nuhertz Technologies, works in conjunction with Modelithics® to synthesize and optimize lumped LC filter designs at frequencies up to at least 5 GHz. The filter circuit synthesis is initially created in FilterSolutions. Modelithics models provide high frequency accuracy, and the discrete optimization is provided in National Instruments’ Microwave Office®.

  • AWR® Fast Axiem® Port Tuning Tutorial

    For exceptionally easy, fast, and accurate planar synthesis and optimizations using Nuhertz with NI AWR Design Environment/AXIEM® 3D planar EM simulator, see application note, Nuhertz ANAWR103 MiniHairpin Filter.pdf. 

  • Miniaturized Hairpin Filter Design with FilterSolutions® and Sonnet Software’s em® Analysis Program in Microwave Office®

    This application note illustrates the technique for creating a design for a miniaturized microwave hairpin filter design. The paper follows the synthesized design created by FilterSolutions® as it is optimized by using the Sonnet electromagnetic analysis program. Further processing for simulation and optimization of the circuit is made possible in NI-AWR Corporation’s Microwave Office® program, an important tool used in this study.
