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.
Halloween isn’t just a time for creative costumes. Thanks to the element14 online design community, the holiday this year also brings us a number of creative electronic device design ideas aimed at making your Halloween party a unique experience.
On April 15, 2010, President Barack Obama gave a major speech at the Kennedy Space Center in Florida, announcing that the US would send astronauts to Mars by the mid-2030s. But in order to do so, NASA would first need to ramp up its capabilities through missions directed toward "a series of increasingly demanding targets," i.e. asteroids.
