Abstract
A phased array antenna may include a substrate and a plurality of phased array antenna elements carried thereby, and an element control module for at least one of the phased array antenna elements. The element control module may include an amplifier coupled to the at least one phased array antenna element and having a controllable bias, and a controllable device coupled to the amplifier and having at least one of a controllable phase, delay, and attenuation. The element control module may also include a control application specific integrated circuit (ASIC) for controlling the controllable phase, delay, and/or attenuation of the controllable device and the controllable bias of the amplifier.
