A beamformer for performing analog beamforming of ultrasound signals received from a plurality of transducer devices, the beamformer includes: first analog devices (310) configured to output first ultrasound signals by delaying or transmitting the ultrasound signals based on a predetermined delay time; second analog devices (320) configured to store first sub-ultrasound signals from among the first ultrasound signals, and to output the first sub-ultrasound signals depending on whether the first sub-ultrasound signals are repeatedly used; and to perform the analog beamforming by summing the first ultrasound signals which correspond to the plurality of transducer devices and which are outputted depending on the delay time.
