Marki Microwave uses Microwave Office for revolutionary mixer design
The revolutionary mixer design flow combines AWR’s Microwave Office® circuit design software and Marki’s patent-pending Microlithic™ mixer manufacturing process, resulting in a 14x reduction in the size of Marki’s mixers and a 5x reduction in design time with the same industry-leading quality and performance as the former handcrafted devices. As a result of the intimate coupling between modeling and fabrication, these mixers are also provided by Marki in the form of accurate, realistic, and fully multi-dimensional electrical models that can be readily integrated within the AWR Microwave Office ecosystem.
Marki Microwave implemented a complex design cycle. First, passive structure models were created using conventional techniques. Next, these structures were integrated with nonlinear diode models and simulated using the Microwave Office® APLAC® harmonic balance simulator. Through careful control of the model parameters, these models were refined until the targeted results were produced, which were used to refine the passive structures. When units were finally fabricated, the simulation results were accurate enough to pinpoint and troubleshoot test problems. Finally, measurement data was used to refine the model parameters before release of the models to Marki’s customers.
Mixer devices are available today from Marki Microwave. Models ML1-0113 and ML1-0220 cover frequencies up to 20 GHz are available for purchase, with several models covering up to 50 GHz currently in pre-production.
The electrical models of the mixers for use within AWR’s Microwave Office software are made available upon request from Marki at www.markimicrowave.com/Microlithic. These models harness the industry leading accuracy of the Microwave Office APLAC® harmonic balance simulator to offer unprecedented simulation capability for RF system designers.
