Abstract
In one embodiment, an integrated circuit antenna array includes: a substrate, a plurality of antennas adjacent the substrate; and an RF network adjacent the substrate, the RF feed network coupling to a distributed plurality of amplifiers integrated with the substrate, wherein the RF feed network and the distributed plurality of amplifiers are configured to form a resonant network such that if a timing signal is injected into an input port of the RF network, the resonant network oscillates to provide a globally synchronized RF signal to each of the antennas.

An integrated RF feed network, comprising:
- a substrate;
- a waveguide network formed adjacent to a surface of the substrate, wherein the substrate includes a plurality of driving amplifiers and matching amplifiers arranged in pairs, the waveguide network being segmented into transmission line segment pairs, each transmission line segment pair having a first segment of length TL1 and a second segment of length TL2, each segment corresponding to a driving amplifier and matching amplifier pair, wherein for each segment the corresponding driving amplifier amplifies the RF signal through the segment to the corresponding matching amplifier, and wherein the waveguide network and the amplifier pairs are configured to form a resonant network such if a timing signal is injected into an input port of the waveguide network, the resonant network oscillates to provide a globally synchronized RF signal at a plurality of output ports.
