Analog beamformer

An analog beamformer comprising:

• 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 receive the first input signal and delay the first input signal by a beamforming delay time to output a first delayed signal;
• a second delay circuit configured to receive the second input signal and delay the second input signal by the beamforming delay time 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 controlling an input of the first delay circuit has the phase difference corresponding to the first phase with respect to a second write signal controlling an input of the second delay circuit, and a first read signal controlling an output of the first delay circuit has the phase difference corresponding to the first phase with respect to a second read signal controlling an output of the second delay circuit.
