Beschreibung
Zusammenfassung:	An analog beamformer includes: an input circuit configured to receive an input signal to generate a first input signal having the same phase as the input signal and a second input signal having a phase difference corresponding to a first phase with respect to the input signal; a first delay circuit configured to delay the first input signal to output a first delayed signal; a second delay circuit configured to delay the second input signal to output a second delayed signal; and an output circuit configured to output an output signal by summing the first delayed signal and the second delayed signal, wherein a first write signal has the phase difference corresponding to the first phase with respect to a second write signal, and a first read signal has the phase difference corresponding to the first phase with respect to a second read signal.
