Abstract
An apparatus () includes an analog beamformer () that receives a set of analog RF signals. The set of analog RF signals are generated by a corresponding set of transducer elements () receiving ultrasound echo signals. The analog beamformer includes a delay network () with a set of phase shifting networks (). Each phase shifting network of the set of phase shifting networks processes a different one of the analog RF signals of the set of analog RF signals. Each phase shifting network of the set of phase shifting networks adds a delay to the corresponding analog RF signal, producing a set of delayed analog RF signals that are aligned in time. The set of phase shifting networks does not use an inductive element to determine or add the delays. The analog beamformer further includes a summer () that sums the delayed analog RF signals, producing an analog beam sum.
