Abstract
We review OSA’s products for microwave circuit optimization. Emphasis is on recent advances in the state of the art in automated electromagnetic (EM) design. The integrated CAD environment facilitates EM optimization of linear and nonlinear microwave circuits. We combine EM analyses of passive structures with circuit models of active devices for large-signal nonlinear harmonic balance optimization, even for yield-driven design. Designs of a class B frequency doubler and a waveguide mitered bend illustrate the approach and its benefits.
Description
Established in 1983, Optimization Systems Associates Inc. (OSA) provided the microwave community with the state-of-the-art CAD technology. Bandler presented this paper in the Microwave Engineering Europe CAD Workshop at the Hyper’97 Conference in Paris, France. It summarizes OSA’s product offerings as of January 1997.
