“…Following the development of load-pulling techniques [1][2][3][4][5], modern design of nonlinear active circuits usually takes into account the effect of load impedances on the desired performance (gain, DC power consumption efficiency, harmonic or intermodulation product generation, etc). It consists of optimizing the 'load' in order to 'pull' out the whole potential of the device.…”

The proposed active source-pull measurement technique allows the creation of variable source impedances having true unitary complex reflection coefficients (total reflection at any desired phase). Based on the use of a reverse six-port reflectometer, frequency-independent source impedances can be synthesized and the power available from the source can also be calculated. The technique is found to be suitable for multi-tone characterization of microwave devices, for use as mixers or broadband power amplifiers. Experimental validations show that the linear measurement accuracy of the proposed technique is about ±0.007 ± 0.5 • for the reflection coefficients measurements and ±0.15 dB for the transducer gain evaluation while the accuracy for the nonlinear measurements is ±0.01 ± 1 • and ±0.15 dB.
