Normalized gain deviation of the HVPA with and without a power MOSFET linearizer vs. input power at (a) 70 MHz under DC bias voltages (1, 3, 6, 9, and 10 V DC, respectively), (b) under DC bias voltages (11, 12, 13, 14, and 15 V DC, respectively), at (c) 80 MHz under DC bias voltages (1, 3, 6, 9, and 10 V DC, respectively), at (d) 80 MHz under DC bias voltages (11, 12, 13, 14, and 15 V DC, respectively). Normalized gain deviation of the HVPA with and without a power MOSFET linearizer vs. output power at (e) 70 MHz under DC bias voltages (1, 3, 6, 9, and 10 V DC, respectively), and (f) at 80 MHz under DC bias voltages (1, 3, 6, 9, and 10 V DC, respectively).
