    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: A waveguide mechanical phase adjuster includes at least one pair of dielectric rods nominally spaced ¼ wavelength apart and inserted through a corresponding pair of holes in the wall of a waveguide. The holes are dimensioned so that they are in “cutoff” at the top end of the spectral band. An adjustment mechanism sets the insertion depth of the rods, which determines the amount of dielectric loading and, in turn, the insertion phase. Changing the insertion depth changes the dielectric loading, hence the insertion phase. The ¼ wavelength spacing of the rods serves to cancel reflected energy. Additional pairs of dielectric rods can be similarly configured and actuated to increase the range over which the insertion phase can be adjusted. The waveguide mechanical phase adjuster is well adapted for use with power combiners to maintain tight phase coherence between channels.

    Abstract: In one aspect, a Y-splitter includes a first arm having a first port, a second arm having a second port, a third arm having a third port, a fourth arm having a fourth port and a Y-split portion having a first end coupled to the first arm, a second end coupled to the second arm, a third end coupled to the third arm and a fourth end coupled to the fourth arm. The Y-split portion splits a signal from a first signal path from the first port into a second signal on a second signal path and a third signal on a third signal path. A first angle between the second signal path and the first signal path is greater than 90 degrees and a second angle between the third signal path and the first signal path is greater than 90 degrees.

    Abstract: A low-loss band and polarization-selectable gender-selectable transceiver for use with a reflector-type antenna suitable for the E-band frequency allocation as well as other RF bands in which the upper and lower bands are separated by a stop band. In addition to providing the gender-selectable combination of the upper and lower bands for transmit and receive, this topology allows for the selection of transmit, and receive polarizations. A transceiver may transmit and receive on the same or on orthogonal polarizations. Paired transceivers may transmit on the same or on orthogonal polarizations. This is accomplished by integrating a rotatable polarizer (e.g. a ¼ wave plate) and a polarization duplexer (e.g. an orthomode transducer) in a FDD (Frequency-Domain Duplexed) system. The rotatable polarizer allows for selection of both transmit and receive bands and polarizations.
