Abstract: A metal plated plastic article (15) for assembly with other components (13, 14) by a dip soldering process. A high temperature/high strength plastic is selected which has a predetermined amount of glass fiber fill to give the plastic article (15) a coefficient of thermal expansion compatible with the articles (13, 14) to which it is to be soldered. The plastic article (15) is metal plated by a method including the steps of surface roughening by abrasion followed by exposure to a particular chemical etch solution followed by chemical plating and electrolytic plating as required. The plating method results in a plated plastic article (15) having a plating peel strength high enough to withstand a soldering process to other articles (13, 14) by means of complete immersion of the articles (13, 14, 15) in a heat medium. The metal plated plastic article (15) is dried, flux is applied to the surfaces to be soldered, solder is applied to the fluxed surfaces, and the assembly of articles (13, 14, 15) is immersed in a heat medium such as hot oil or hot vapor, at a temperature of at least 232 C for a time sufficient to permit solder reflow between the assembled articles (13, 14, 15).

Abstract: A millimeter-wave phase shifter for use at high millimeter-wave frequencies. The phase shifter employs continuous aperture ferrite and corrugated horns to make a reciprocal phase shifter in the frequency range of interest. Applied linearly polarized energy is expanded in cross-section by means of a first corrugated horn (23). The expanded energy is focused by a first lens (27), circularly polarized (24) and applied to a ferrite phase shifting section (22). The phase shift applied to the energy is controlled by means of phase control circuitry (28) and a yoke (31) and coil (32) arrangement. The phase-shifted energy is then converted to linearly polarized energy by a second circular polarizer (34) focused by a second lens (37) and contracted in cross-section by a corrugated horn (38). The use of the corrugated horns, polarizers, lenses and ferrite phase shifting components allows a much larger device to be fabricated and hence physical tolerances are reduced by an order of magnitude for the frequency range of interest. In addition, both the efficiency and power handling capability are greatly improved. Both reciprocal and nonreciprocal phase shifters are disclosed.

Abstract: Circular waveguide (12) in which slots are formed which are shaped and disposed such that they interrupt either the right hand or left hand circulating mode (RC and LC respectively) residing in the waveguide (12). Locating the slots in the waveguide (12) wall is accomplished in accordance with the theory that for TE modes in circular waveguide with circumferential variation of e , current flow lines (38, 40) are produced that are helical. The slots (14) are located so as to interrupt the helical currents of the desired mode. In one embodiment, an ortho-polarization mode transducer (20) and a circular polarizer (16, 18) are used to feed the slotted waveguide (12). By controlling the amplitude and phase of the energy propagating in the waveguide (12), azimuthal pattern control can be effected. By loading the waveguide with dielectric to make lambda g in the loaded waveguide equal to lambda -free space, endfire radiation can be achieved.

Abstract: A parallel plate radial transmission line (14) having parallel plate spacing of less than lambda /2 and which utilizes a specific higher order mode, preferably the first higher order circumferential mode. Undesired modes are suppressed by mode suppression slots (66) formed in one or both of the parallel plates and which are oriented parallel to the current flow lines (68) of the particular mode that is used. These slots (66) have a negligible effect on the mode being used but they couple out other modes that are generated by means such as by imperfections and imbalances in any active devices (36) coupled to the radial line. A centrally located feed is used to launch circularly polarized energy of the TE11 mode in the particular circumferential mode in the radial line (14). The feed may also receive circularly polarized energy of the particular circumferential mode in the radial line, linearly polarize that received energy and conduct it in the TE11 mode.

Abstract: Disclosed is an around the mast rotary joint capable of multichannel operation. There are two hollow coaxial sections (18, 20), each of which operates in the TEM or quasi-TEM mode. Each section comprises a coaxial feed line (16, 14) connected to a microstrip corporate feed network which is cylindrical (24, 40). Coupled to the microstrip corporate feed is a low impedance cylindrical interface section (22, 40) which couples the power to the other coaxial section. In addition to evenly feeding the interface section, the microstrip network includes impedance transformers and matching means to match the relatively high impedance of the coaxial feed line to the relatively low impedance of the interface section. The two sections are coupled together with a noncontacting choke (54).

Abstract: A power divider/combiner using two parallel plate radial transmission lines (14, 16) having parallel plate spacing of less than lambda /2 and which operates in a higher order mode, preferably the first higher order circumferential mode TE11. High isolation between amplifiers (34) coupled to the radial transmission lines at their circumferences is achieved by coupling an arrangement of circulators (30, 32, 36) between the amplifiers (34) and the radial transmission lines (14, 16). This isolation arrangement reduces the effects of any spurious signals that are generated by means such as imperfections and imbalances in any active devices coupled to the radial line and permits de-energizing amplifiers as desired for lowering power output without degrading performance.

Abstract: An electronically scanned array antenna (18) useful for millimeter wavelength energy. The antenna comprises a fully ferrite (21) loaded square or round waveguide (20) having radiating apertures (22) spaced along part of its length. Rf energy is circularly polarized (26) in the waveguide. The phase velocity of the wave is controlled by applying a longitudinal magnetic field to the ferrite to produce a controllable linear progressive phase of the energy radiated from the apertures (22) to form a beam in the desired direction. The phase control (28) is of a latching type using flux drive. The particular structure of the invention enables combining a plurality of branching array elements (66) with a feed element (68) to form an array capable of two dimension beam scanning.

Abstract: Une ligne de transmission radiale à plaques parallèles (14) où l'écart entre les plaques parallèles est inférieur à lambda/2 utilise un mode spécifique d'ordre élevé, de préférence le premier mode circonférentiel d'ordre élevé. Les modes non souhaités sont supprimés par des fentes de suppression de modes (66) formées dans une ou dans les deux plaques parallèles et orientées parallèlement aux lignes d'écoulement du courant (68) du mode spécifique utilisé. Ces fentes (66) ont un effet négligenciable sur le mode utilisé mais déconnectent d'autres modes générés par des imperfections ou des déséquilibres dans tous dispositifs actifs (36) couplés à la ligne radiale. Une alimentation contrale est utilisée pour lancer dans la ligne radiale (14) de l'énergie polarisée du mode électrique transversal (TE11) dans un mode circonférentiel particulier. L'alimentation peut également recevoir de l'énergie à polarisation circulaire du mode circonférentiel particulier de la ligne radiale, donner une polarisation linéaire à l'énergie reçue et la transmettre dans le mode TE11.
