| 研究実績の概要 |
This research introduces low-cost, reconfigurable mmW distributed phased-array transceivers. The deployment of such arrays is much more flexible compared with centralized arrays. To realize compact, low-cost characteristics, this research introduces the neutralized bi-directional architecture. The phased-array gain and stability are enhanced with a minimized area and cost. To maintain high-efficiency characteristics, this research explores Doherty PA with higher efficiency at backoff. To minimize the unwanted radiation, this research first introduces a phase shifter with phase compensation network. The errors are therefore reduced. Furthermore, this research introduces on-chip magnitude and phase detection circuits for correcting the errors between channels.
