    摘要: In a polarization angle adjusting mechanism for an antenna apparatus constructed of a supporting base and a transmitter/receiver apparatus equipped with a primary antenna at a right end portion thereof formed in an integral form, the primary antenna being located at a focal portion of an antenna, the supporting base has a cylindrical bearing for receiving a rotation shaft of the transmitter/receiver apparatus at a left end portion thereof, and also a plurality of subdivided projections are provided on this shaft receiving plane along a circumferential direction. On the other hand, projections and grooves fitted to a plurality of projections provided on the supporting base, which can be inserted among these plural grooves, are provided in the circumferential surface of the rotation shaft of the transmitter/receiver apparatus. The rotation shaft is inserted into the supporting base and the transmitter/receiver apparatus is rotated, so that the projections are fitted to the grooves so as to mount the transmitter/receiver apparatus to the supporting base. Similarly, another supporting base is mounted on the right end portion of the transmitter/receiver apparatus. In this manner, the transmitter/receiver apparatus is rotated to thereby adjust the polarization angle.

    摘要: A branching filter for a transmitter-receiver which is used in a microwave band comprising an orthogonal-mode transducer (waveguide branching filter), a reception filter comprising a band-eliminating filter 4 which is connected to the extension of the center axis of the waveguide of the orthogonal-mode transducer, and a transmission filter comprising a high pass filter containing a cut off waveguide which is directly and orthogonally connected to the orthogonal-mode transducer. The parts of the branching filter for the transmitter-receiver are integrally manufactured as one body by a lost wax process. Therefore, the branching filter for the transmitter-receiver can be manufactured as a compact-size single body having no patch or linking portion.

    摘要: A radio transceiver having an integrated transmitter and receiver for transmitting and receiving microwaves or higher frequency electromagnetic waves is one of a series of device products corresponding to different transmission output power capacities. In this invented series of device products, a radio transceiver which is of a minimum size to meet its transmission output power requirement without an amplifier is composed of entirely standardized basic components, a transmission module, a reception module, and a transmission and reception shared circuit which are housed in a heat radiating housing case irrespective of different transmission output power requirements. Corresponding to the transmission output power requirement, a power amplifier is added to the basic components. The heat radiating housing case which houses the basic components and the power amplifier is longer than, but has the same cross section as, the heat radiating housing case which houses no power amplifier, thereby radiating the heat produced by the power amplifier. The heat radiating housing case is thus substantially standardized.

    摘要: In a branching filter, a transmit filter (14) is divided into first and second transmit filter parts (17, 18). A waveguide branching filter (15) is divided into first and second branching filter parts (19, 20). A receive filter (16) is divided into first and second receive filter parts (21, 22). The first transmit filter part is assembled with the second branching filter part and the second receive filter part. The second branching filter part is assembled with the second receive filter part. The first branching filter part is assembled with the first receive filter part. Alternative assembly is possible. As a further alternative, an installation hole may be formed in the branching filter for removable installation of a cable and be covered with a cover with a packing interposed for hermetic seal and waterproofing.
