Block diagram of measurement system when using (a) transmit amplifier only and (b) transmit amplifier with dual-bias high-voltage circuit, (c) spectrum data of transmit amplifier with dual-bias high-voltage circuit at 10 V DC voltage, and (d) HD2, HD3, HD4 and THD values with and without dual-bias high-voltage circuit vs. 0.8 V, 5 V, 10 V, 15 V and 20 V DC voltages (graph with dash, dot, dash-dot and solid marks represent HD2, HD3, HD4, and THD, respectively, of the transmit amplifier with dual-bias high-voltage circuit). HD2 w/o, HD3 w/o, HD4 w/o, THD w/o represent the measured HD2, HD3, HD4, and THD of the output signals, respectively, when using transmit amplifier only.
