The concept of load pull may not be that clear to many Design News readers since, while it does sort of have a mechanical equivalent, it has not been talked about by this name outside of the RF amplifier design realm very much.
Load pull is the effect on the amplifier output caused by chyanges in the downstream load impedance driven by the amplifier's output power. It may often be quite nonlinear, which makes modeling a bit more challenging. Also, the effect may work in both directions, making evaluation and analysis more complex and challenging.
The problem with a four-, five-, or six-year degree is that they don’t teach engineers the soft skills required to have a successful career. Here are seven skills that every engineering graduate needs to be successful.
Design teams are operating in a business environment that increasingly requires them to collaborate and share data across extended teams, multiple organizations, and widespread locations. Autodesk’s customers are looking for a solution that eliminates project bottlenecks, such as the time-consuming and error-ridden process of shuttling design reviews and revisions back and forth among team members.
