1. A scalable analog beamforming system, comprising:

  • a plurality of time delay unit (TDU) modules, each of the TDU modules comprising TDU controller circuitry and each given one of the TDU modules being configured for coupling to at least one different array element of a phased array apparatus to receive and change at least one of the phase, amplitude, or combination of phase and amplitude of a signal received from or transmitted to the array element by the given TDU module under the control of the TDU controller circuitry; and

    master control circuitry coupled to control the TDU controller circuitry of each of the TDU modules, the master control circuitry being configured to digitally control the TDU controller circuitry of each of the TDU modules to change the phase of a signal received from or transmitted to the array element.
