Harmonic Load Pull with High Gamma Tuners

Automated load pull has become a standard tool for characterizing microwave power devices. Power devices operate in a nonlinear mode in order to achieve reasonable efficiency, so testing must be done with actual drive power and impedance matching. This...

Microwave power devices, widely used in modern wireless and communications systems, must operate in a nonlinear mode in order to operate efficiently. Nonlinear operation means that the only valid way to test them is under actual operating conditions of DC bias, RF power and impedance. Small-signal S-parameters are not...
