Abstract: A communications system having two terminals, each including two antennas, the communications system using spatial multiplexing. One antenna of a first terminal transmits a tracking tone along with a data signal. Two antennas in a second terminal receive the tracking tone. The signals from the two antennas are processed by a feed circuit. The feed circuit includes a variable delay circuit and a combiner that forms, at a first difference output, a linear combination, of a signal from the first antenna and a signal from the second antenna, in which the tracking tone is canceled. The variable delay circuit is actively adjusted to maintain this cancellation.

Abstract: An apparatus for conveying an electrical signal includes: a conductive pathway having a conductive material. The conductive material has a first edge and a second edge and is configured to convey the electrical signal. The apparatus also includes a resistive material in contact with at least a portion of the conductive pathway, covering an edge of the conductive pathway, and extending beyond the edge. The resistive material has a conductivity less than the conductivity of the conductive material.

Abstract: A power amplifier uses a modular architecture in which each of the one or more modules spatially combines the power from multiple amplified channels. The individual modules are configured to operate in the EHF band and above at low loss. This entails reconfiguring the input and output splitters, the end-launched transitions between the amplifier chips and the input and output splitters and the packaging of the DC power and control board. The input splitter uses a split-block technology. The output splitter maps each amplified channel into a two-dimensional aperture.
