The half-power point is the point at which the output power has dropped to half of its peak value; that is, at a level of approximately -3 dB. In filters, optical filters, and electronic amplifiers, the half-power point is also known as half-power bandwidth and is a commonly used definition for the cutoff frequency. In the … See more This occurs when the output voltage has dropped to $${\displaystyle 1/{\sqrt {2}}}$$ (~0.707) of the maximum output voltage and the power has dropped by half. A bandpass amplifier will have two half-power points, while a See more In antennas, the expression half-power point does not relate to frequency: instead, it describes the extent in space of an antenna beam.
