An integrated signal chain includes a waveguide network defined by first and second waveguide layers forming a waveguide stack. A first transmit waveguide channel (WGC) is configured to communicate first transmit electromagnetic signals from a first transmit port to an antenna feed port, and a first receive WGC is configured to communicate first receive electromagnetic signals from the antenna feed port to a first receive port. A transmit module is attached to an exterior side of the first waveguide layer, and the first transmit WGC couples the transmit module to the antenna. A receive module is attached to the exterior side of the first waveguide layer, and the first receive WGC couples the antenna to the receive module. A modem may be included. A thermal management assembly can be configured to dissipate heat from the modem, the receive module, and/or the transmit module.

Integrated signal chain for an antenna assembly

In one embodiment, a waveguide assembly includes a first waveguide portion having a first end, a second end, and a first waveguide channel extending between the first end and the second end, and a second waveguide portion having a first end, a second end, and a second waveguide channel extending between the first end and the second end, wherein the first waveguide portion and the second waveguide portion are configured to connect such that the first waveguide channel and the second waveguide channel form a combined channel, wherein the combined channel includes a gap interface between the first waveguide channel and the second waveguide channel.

In one embodiment, a parabolic antenna assembly includes a main reflector, a feed system in RF communication with the main reflector including a horn and a dielectric portion, and a sub-reflector in RF communication with the feed assembly, wherein the sub-reflector includes a body portion and a stem portion mechanically coupled to one another, wherein a reflecting surface of the sub-reflector is defined by at least a portion of the body portion and at least a portion of the stem portion, wherein the dielectric portion spaces the sub-reflector from the horn, and wherein the sub-reflector includes an axially-symmetric choke for providing virtual continuity at the reflecting surface.
