Rohde & Schwarz Wideband Modulated Load Pull: The Test That Deliberately Breaks Your Amplifier

Rohde & Schwarz Wideband Modulated Load Pull: The Test That Deliberately Breaks Your Amplifier

Load pull testing deliberately varies impedance away from the ideal operating point — until the amplifier's behavior is fully mapped. At the microwave show, R&S showed why wideband modulated load...
