1. A beam forming integrated circuit for use in a phased array system, the beam forming integrated circuit comprising:
a plurality of beam forming channels, each beam forming channel including beam forming circuitry configured to process signals for a beam forming element to produce a beam-formed signal; and
for each beam forming channel, at least one individually addressable and programmable register set configured to store operating parameters for the beam forming channel, wherein a selected register set associated with each beam forming channel is pre-programmed with operating parameters for changing directivity characteristics of the beam-formed signal; and
fast beam switching circuitry that receives fast beam switching control signals from a fast beam switching control interface, the fast beam switching circuitry configured to simultaneously switch each beam forming channel to the pre-programmed operating parameters from the selected register set associated with the beam forming channel based on the fast beam switching signals from the fast beam switching control interface to change the directivity characteristics of the beam-formed signal.
