Abstract: A flared feed horn including a plurality of signal lines deposited on a bottom surface of a substrate and forming part of a TE11 sum mode launcher, a ground plane deposited a top surface of the substrate, and an outer conductor electrically coupled to the ground plane and having an internal chamber, where the conductor includes a flared portion and a cylindrical portion. The outer conductor includes an opening opposite to the substrate defining an aperture of the feed horn. The feed horn also includes an embedded conductor positioned within the chamber and being coaxial with the outer conductor, where the embedded conductor is in electrical contact with the plurality of signal lines. The feed horn also includes a TE12 difference mode launcher electrically coupled to the outer conductor proximate the aperture.

Abstract: A waveguide-to-microstrip transition (30) for converting and directing electromagnetic wave signals to an electronic signal processing component (53). A waveguide (32) directs the signals to a waveguide input and is received by a probe (36). A bent microstrip line (40A) which is connected to the probe (36) directs the received signals from the probe (36) to the electronic signal processing component (53). An output port (43) provides a connection between the bent microstrip line (40A) and the electronic signal processing component (53). The output port (43) is not inline with respect to the probe (36), but the microstrip line (40A) includes a bend so as to direct the received signals from the probe (36) to the output port (43).

Abstract: An SSPA module in accordance with the present invention comprises a signal input (102), and a radial splitter (100) connected to the signal input (102) comprising a plurality of radially extending splitter waveguides 104, 106, 108, 110, 112, 114, 116, 118, 120, 122, 124, 126. The SSPA module also includes a signal output (202), and a radial combiner (200) connected to the signal output (202) comprising a plurality of radially extending combiner waveguides 204, 206, 208, 210, 212, 214, 216, 218, 220, 222, 224, 226. Connections between the splitter (100) and combiner (200) are provided by a plurality of vertically extending waveguides 404, 406, 408, 410, 412, 414, 416, 418, 420, 422, 424, 426. The SSPA module also includes a plurality of processing circuits 304, 308, 308, 310, 312, 314, 316, 318, 320, 322, 324, 326, for example MMIC amplifiers, connected to the combiner waveguides 204, 206, 208, 210, 212, 214, 216, 218, 220, 222, 224, 226.

Abstract: A waveguide-to-microstrip transition package (30) for processing electromagnetic wave signals includes a waveguide (32) for directing the signals to the input of the waveguide (32). A substrate (34) overlaps the input of the waveguide (32) to form a hermetic seal. A metallized probe (36) conducts the signals to a microstrip line (40) and is patterned upon the substrate (34). The transition (30) also includes an iris (48) formed from a metallized pattern on the opposite side of the substrate (34) from the probe (36). The special design of the probe (36), the structure of the iris (48) and the wave guide cavity (46) above the probe (36) allow impedance matching and efficient signal transfer from waveguide (32) to microstrip line (40) or from microstrip line (40) to waveguide (32).

Abstract: A microwave radial power divider/combiner device having desirably broad bandwidth response over a selected frequency range. The device includes a radial waveguide that has a number of adjoining annular sections, each of selected radial length and axial height, to provide lumped circuit parameters closely euqivalent to those of an ideal filter with the desired passband characteristics. The ideal filter is first designed using conventional synthesis techniques, then modified, if necessary, to allow its realization in radial waveguide form. The waveguide sections are selected to have lengths and uniform heights to approximate the lumped circuit parameters of the filter, and the dimensions are then optimized to provide the closest approach to the desired performance characteristics.
