Reconfigurable input power distribution doherty amplifier with improved efficiency |
| 摘要 |
A novel Doherty amplifier with improved efficiency is disclosed. In an exemplary embodiment an apparatus includes a phase shifter configured to generate a phase shifted first millimeter (MM) wave signal based on a selected phase shift, and a hybrid plus coupler comprising output terminals and configured to adjust output power levels at the output terminals based on combinations of the phase shifted first MM wave signal and a second MM wave signal. |
