Abstract:
A phased array (20) and method for constructing the same are disclosed. The phased array (20) includes a superstructure (22) with cavities (40) therein. A cover plate (28) is mounted to the superstructure (22) and cooperates with the cavities (40) to form cavity style filters therebetween and to form a box-beam type superstructure. Ideally, the superstructure (22) is self supporting. Electronic modules (32) and amplifiers (33) are mounted to the superstructure (22). The method includes machining a block of material to form a webbed superstructure with cavities (40) therein. A cover plate (28) is mounted to the superstructure (22) over the cavities (40) to form cavity style filters. Amplifiers (32) and antenna elements (30) are then affixed to the superstructure (22) and cover plate (28). Ideally, the cover plate (28) is affixed to the superstructure (22) using an electrically conductive adhesive.

Abstract:
A structure for extra-high-frequency circuit modules, to take advantage of the low losses and convenience of assembly of waveguides, and at the same time to take advantage of the ease of tuning of microstrip lines. Each module is adapted to be conveniently connectable to others in a cascade arrangement, and each presents a waveguide interface to adjacent modules. If a module is to contain an active device, such as an amplifier, the module incorporates a microstrip section and two transition sections to couple the microstrip section to the waveguides at input and output. The microstrip section is easily tunable and is easier to couple to the active device.

Radial Wave Power Divider/Combiner And Related Method

International Classification:
H01P 512
US Classification:
333125
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.
