Bandwidth comparison for BL-DPD and proposed DPD.
| | | Baseband rate (MSPS) | ADC sampling rate (MSPS) | Tx BW (MHz) | DAC sampling rate (MSPS) | FB BW (MHz) |
| | 80 MHz scenario | | BL-DPD | 737.28 | 184.32 | 144 | 184.32 | 144 | | Proposed DPD | 184.32 | 184.32 | 144 | 184.32 | 144 |
| | 320 MHz scenario | | BL-DPD | 2949.12 | 737.28 | 576 | 737.28 | 576 | | Proposed DPD | 737.28 | 737.28 | 576 | 737.28 | 576 |
