Abstract: A reconfigurable beam-forming network for use with a transmitter has a waveguide R-switch that is interconnected with a Magic T. The R-switch contains phasing elements and is connected to a dual-mode power-­dividing network, which in turn is connected to first, second and third region power-dividing networks, each having their own feed horn array. The R-switch can be moved to three different positions so that in a first position power is divided between two input ports of the dual-mode network on substantially a fifty-fifty basis with the power on the two input ports being out of phase on a positive basis. In a second position of the R-switch, power is also divided on substantially a fifty-fifty basis between the two input ports but the power is out of phase between the two ports on a negative basis. In a third position of the R-switch, substantially all of the power entering the R-switch is passed into the first input port of the dual-mode network. The power being fed to the feed horns of any one of the regions has the same phase. In a variation of the invention, the R-switch and Magic T are replaced by a variable phase shifter and Magic T.

Abstract: A transmission line circuit assembly 200 has a substrate layer 100 having a transmission line trace, further having a functional portion 128 and a transitional portion 124. An enclosure of the assembly houses the transitional portion 124 of the transmission line trace. A first surface 280 of a dielectric plug 272 is conductively coupled to an inner top surface of the enclosure. A second surface 288 of the plug 272 is aligned and spaced apart from the transitional portion 124 of the transmission line trace to define a gap 296 therebetween. An interfacing portion 320 of a connecting pin 312 is housed within the enclosure and bonded to the transitional portion 124. A connecting portion 328 of the pin 313 is connectable to an external conductor. The gap 296 may be filled with a dielectric material. The transitional portion 124, dielectric plug 272, dielectric filler 376 and connecting pin 312 form an electromagnetic transition providing tuning and matching of the function portion with the external conductor.

Abstract: A microwave filter has a housing defining an inner cavity. A first resonator is positioned in a first portion of the inner cavity. A second resonator is positioned in a second portion of the inner cavity. A third resonator is positioned in a third portion of the inner cavity. The first resonator and the third resonator are cross-coupled via an iris. The second resonator is elongated and is coupled to the first resonator and the third resonator. The resulting microwave filter has a frequency response having a transmission zero in the lower stopband. A high-pass filter is realized without the use of a cross-coupling probe.

Abstract: An analog processor for use with digital satellites is disclosed. The analog processor is connected between the receiving circuitry of the satellite and a pool of digital on-board processors, and segments the bandwidth of uplink RF beams into sub-bands that can be processed more readily with standard, low-risk, low-power digital processors. Using the present invention, the risk of employing a particular digital processor technology can be managed and optimized. The present invention also provides for the dynamic allocation and reallocation of the available on-board digital processing bandwidth based on the anticipated traffic pattern and changes in the traffic pattern. In addition, the present invention facilitates the use of standard and non-standard redundancy schemes at minimal hardware expense.

Abstract: A hybrid switch actuator having six positions that are stable in the absence of current and in which displacement occurs between an initial position and a target position under the action of a current. The actuator includes a stator and a rotationally moveable rotor package. The stator has six pole shoes. Each pair of opposed pole shoes is equipped with a common exciting coil. The rotor package has two pairs of rotor poles magnetized transversely in alternate directions and a permanent magnet ring and two end caps adapted to be engaged around said permanent magnet. ring. Each end cap is associated with two rotor poles having maximum radius regions that correspond to the area of each of the stator pole shoes and reduced radius regions positioned adjacent the maximum radius regions such that each rotor pole can be precisely aligned with each stator pole shoe.
