We report a GaN Voltage-Mode Class D power amplifier designed for use at 465 MHz of LTE Band 31. The amplifier is fabricated as an integrated circuit including switching circuit that employs two stacked GaN FETs, and drivers for each GaN FET. A bootstrap-drive configuration is used in order to increase the driver-stage efficiency for the uppermost GaN FET. The GaN VMCD amplifier achieves peak power-added efficiency of 66.6%, and an output power of 3.3W. At 6dB power back-off, power-added efficiency of 36.3% is achieved. |
