This work discusses several extraction procedures for the recently proposed dual input-dual output (DIDO) low pass equivalent behavioral model according to their required excitation signals. These methods are based on passive load
pulling and uncontrolled open loop active load pulling but with different type of excitation waveforms. It also addresses the
hardware and signal conditioning of the proposed extraction procedures in detail. The performance of the discussed methods
are compared based on the datasets extracted from simulation results in ADS. The results show that the use of the active loadpulling can enhance modeling performance.
