Fundamentally Changing Nonlinear Microwave Design

Nonlinear: "Of or relating to a device whose behavior is described by a set of nonlinear equations and whose output is not proportional to its input." -The American Heritage® Dictionary of the English Language, Fourth Edition
S-parameters have been used to represent linear networks for simulation and design since the 1960s. Measuring S-parameters was made possible with the introduction of the network analyzer. Designers could then integrate S-parameter "black-boxes" along with other electrical components using linear frequency-domain simulators. The measure, model and simulate triumvirate has...

Choosing the Optimal High Frequency Coaxial Cable

Operating frequencies for coaxial transmission lines have steadily climbed from below 1 to 110 GHz and beyond over the last few decades. This has caused RF/microwave engineers to search for coaxial transmission lines capable of effectively transmitting...
Coaxial cable derives its name from the spatial relationship shared between the center conductor and the outer conductor. Figure 1 shows this "co-axial" positioning of conductors. A British engineer and mathematician by the name of Oliver Heaviside first patented the basic design of coaxial cable in 1880 (Patent Number:...
