Abstract: A balun design incorporating the functions of a splitter (combiner) which can be employed in a high power amplifier circuit configuration. The balun is formed of a dielectric multilayer board with conductor patterns on each conductor pattern layer. The balun includes the propagation of a half of an input signal to an in-phase output terminal, and also propagating a fourth of the input signal to first and second opposite-phase output terminals, the signal propagated to the first and second opposite-phase output terminals lagging 180 degrees behind the signal propagated to the in-phase output terminal. The balun provides the output signals at the first and second opposite-phase output terminals 180° out of phase employing through holes in the main line and coupling lines for promoting electromagnetic coupling therebetween.

Abstract: A dielectric duplexer device is provided with an output terminal pad formed on a side surface of a dielectric block in the vicinity of an open end associated with a plurality of resonators of a reception section in such a manner as to face the resonators. An extension electrode extends from the output terminal pad onto an end face of the dielectric block where the open end is present, to thereby be capacitively coupled with the resonators. The coupling capacitance can be readily corrected by adjusting the position of the end of the extension electrode. In one specific form, when the dielectric duplexer is mounted, the extension electrode is exposed and is also joined to a predetermined conductive path by means of solder. Accordingly, the output terminal pad is soldered at the bottom and side surfaces thereof to thereby be fillet-soldered, thereby providing visibility of electrical and mechanical connections thereof to the predetermined conductive path and thus enhancing the reliability of the mounted state.

Abstract: A dielectric filter capable of easily obtaining desired filter characteristics by strongly coupling mutually adjacent resonators with high accuracy even when reducing the height of the entire filter. In this filter, inside a dielectric block, there are disposed inner-conductor-formed holes in which inner conductors are formed on the inner surfaces of the holes. Coupling electrodes are arranged on an outer surface of the dielectric block and are electrically connected to the inner conductors. Additionally, the coupling electrodes are extended, for example, from the edge of an opening surface of the dielectric block which contains the open ends of the inner-conductor-formed holes, onto a side surface which is disposed parallel to a direction in which the inner-conductor-formed holes are aligned. The invention also provides a duplexer and a communication apparatus using the dielectric filter.

Abstract: A waveguide type duplex filter having first and second waveguides which each comprise filtering means tuned to a given frequency, comprises two halves having a conducting surface. Faces directed toward each other are formed with channels which, when the halves have been assembled, constitute said waveguides. The filtering means are produced by means of a sheet having a conducting surface arranged between the two halves, and the conducting surface has openings which define and delimit resonators in the waveguides. The sheet can be arranged in first and second positions. In the first position, the resonators in the first waveguide are tuned to a first frequency, while the resonators in the second waveguide are tuned to a second frequency. In the second position, the resonators in the first waveguide are tuned to the second frequency, while the resonators in the second waveguide are tuned to the first frequency.

Abstract: A multi-channel feed network includes a main waveguide section (either square or circular) for connection to a satellite antenna for propagating two orthogonal polarizations. The feed network further includes a low pass section connected on axis with the main waveguide, the low pass section having the same cross section as the main waveguide, and a high pass section also connected perpendicular to the main waveguide. The low pass section includes a band reject filter (BRF) formed from slots cut to reject higher frequency signals. The high pass section can be a rectangular waveguide which functions to filter low frequency signals. The feed network can be configured to support a number of different polarizations. Orthogonal linear polarizations are provided for the high frequency bands by adding additional high pass sections connected by power dividers, and for the low frequency bands by adding a conventional OMT. Adding a polarizer between the antenna and main waveguide section enables both the high pass and low pass sections to support left or right hand circular polarization. By adding a 90° degree hybrid coupler, the high pass section can support circular polarization alone. By adding a polarizer and OMT after the low pass section, the low pass section can support circular polarization alone. By using two 90° degree hybrid couplers and two power dividers, a network can be created to support dual circular or linear polarizations.

Abstract: A coaxial turnstile junction (10) for combining and directing both satellite uplink and downlink signals. The junction (10) includes a tapered section (30) to provide better impedance matching of the downlink signal between a waveguide structure (14) and a plurality of symmetrically disposed downlink waveguides (38-44). The junction (10) includes a first end (26) that is in signal communication with an antenna feed horn (12). The junction (10) includes a cylindrical outer wall (28) and a cylindrical inner wall (18) that are coaxial and define an outer chamber (22) and an inner chamber (24). The outer wall (28) extends into the tapered section (30) where the tapered section (30) contacts the inner wall (18) and closes the outer chamber (22). The waveguides (38-44) are positioned around the outer wall (16) and are in signal communication with the outer chamber (22) through openings in the tapered section (30). Irises (46-52) are provided at the connection between the downlink waveguide (38-44) and the outer chamber (22) for impedance matching purposes. Satellite downlink signals from the downlink waveguides (38-44) are sent to the feed horn (12) through the outer chamber (22). Satellite uplink signals received by the feed horn (12) are directed through the inner chamber (24) to receiver circuitry. The dimensions of the irises (46-52) and the flare angle of the tapered section (30) are selected and optimized so that the downlink signal propagating down the waveguides (38-44) is impedance matched to the downlink signal propagating through the outer chamber (22).
