This paper presents, for the first time, a waveform/time-domain measurement system with active harmonic load pull that is capable of characterising 100W LDMOS devices. In order to achieve the required high-power capability the measurement system employs a new bias-tee design (Benedikt and Tasker, 2002) coupled with broadband impedance transformers (Aboush et al., 2004). The unique characteristics of the high-power bias-tee increases the performance of the measurement system up to 12GHz, 100W CW… CONTINUE READING
