PURPOSE: A power detect device is provided to have advantage of performing power detection of RF signal quickly and precisely. CONSTITUTION: The power detect device(20) includes a phased array transform part and a power detect part. The phased array transform part(210) diversifies the phase of the radio frequency signal (V1(t)) to measure electric power differently at each transition point of time. The power detect par detects the electricity of the radio frequency signal which the phased array transform part changed the phase. |
