ABSTRACT:
A monolithic gallium arsenide (GaAs) phased array using integrated gold (Au) posts for interconnecting multiple substrate layers. The phased array includes a GaAs substrate having transmit/receive modules fabricated on one side and radiating elements etched on the backside of the same substrate. The conductive gold posts are integrated on the same side with the transmit/receive modules and interconnect the transmit/receive modules with a distribution network which is printed on a second substrate. Gold posts are also used to interconnect DC bias and control lines of the two substrates.
