Abstract: 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.
