摘要： A transmission module including a power supply voltage control unit that sets a power supply voltage to the high frequency amplifier in a variable manner, and a control circuit that controls an amplitude control unit, a phase control unit and the power supply voltage control unit. The control circuit and the power supply voltage control unit control the power supply voltage in accordance with an output power of the high frequency amplifier. The transmission module can carry out not only phase control but also amplitude control in a continuous manner, while suppressing amplitude and phase variation, and a high frequency amplifier in the transmission module is made highly efficient. In addition, a large directional gain, a low side lobe level and a low power consumption are achieved, as a phased array antenna apparatus using a transmission module.

摘要： Other end of a built-in optical fiber of a ferrule with one end of the built-in optical fiber matched with a splicing end surface and other end of the built-in optical fiber protruded from an end portion opposite to the splicing end surface and one end of a splicing optical fiber to be spliced are placed is fusion-sliced with the one end of the splicing optical fiber. After that, the ferrule is held by inserting a cylindrical portion of the ferrule into a holding unit of a ferrule holder from the splicing end surface. The ferrule is transferred while holding a stem extended on an opposite side of the holding unit of the ferrule holder and the splicing optical fiber.

摘要： An optical control type phased array antenna includes a laser generating means for generating light of single wavelength, an optical path branching means for branching the light emitted from the laser generating means into first and second transmission lights, a high frequency signal generating means for generating a high frequency signal, an optical frequency modulating means for shifting the frequency of the first transmission light branched by the optical path branching means by the frequency of a high frequency signal thus generated, a spatial light phase modulating means performing spatial phase modulation of the first transmission light shifted by the frequency of a high frequency signal depending on the antenna beam pattern, and an optical path branching/multiplexing means for multiplexing the first transmission light subjected to phase modulation and the second transmission light branched by the optical path branching means. Optical path lengths of two paths between the optical path branching means and the optical path branching/multiplexing means are equalized.
