Abstract
In one aspect, an active electronically scanned array (AESA) tile includes a radiator structure and oxide-bonded semiconductor wafers attached to the radiator structure and comprising a radio frequency (RF) manifold and a beam former. An RF signal path through the oxide-bonded wafers comprises a first portion that propagates toward the beam former and a second portion that propagates parallel to the beam former.
Claims19
An active electronically scanned array (AESA) tile comprising:
- a radiator structure;
- and
- oxide-bonded semiconductor wafers attached to the radiator structure and comprising a low loss glass radio frequency (RF) manifold and a beam former, wherein the RF manifold is not in direct contact with the beam former;
- wherein an RF signal path through the oxide-bonded semiconductor wafers comprises a first portion that propagates toward the beam former, a second portion that propagates parallel to the beam former, a third portion that propagates away from the beam former, and a fourth portion that extends into the beam former and out of the beam former;
- wherein the RF signal path moves along three axes,
- wherein the first portion, the third portion and the fourth portion of the RF signal move in a Z-axis direction,
- wherein the second portion of the RF signal moves in an X-axis direction, and
- a fifth portion of the RF signal moves in a Y-axis direction.
