Experimental measurements for the expanders. (A) The experimental arrangement used to measure the IL of the expanders, (B) IL of the expanders when a 70 Vp-p pulsed sine waveform from the power amplifier was applied, (C) experimental arrangement for the NF measurement and (D) NF of the expanders. “Diode” refers to the commercial diode-based expander (DEX-3) and “SMPS MOSFET” refers to the crossed SMPS MOSFET-based expander.
