摘要： Apparatus for transmitting a collimated and directed beam of wave energy which includes a beam-forming network having a plurality of amplification sections coupled to an array of transmitting elements. Each one of the sections includes: a source of digital samples of the wave energy; a digital filter fed by digital samples for providing a time delay to the replica; and an amplification system. The amplification system includes: a bridge amplifier producing a feedback signal representative of current passing through a bridge circuit; an analog to digital converter section to produce a corresponding digital feedback signal; a digital summer fed by digital samples of a signal to be amplified and by the digital feedback signal for producing a composite digital signal; and a modulator section fed by the composite digital signal and the carrier signal source produced signal for producing the plurality of switching signals for the amplifying elements.
