Synthesizer and transmitter for digital amplitude modulation for transmitter

摘要

PROBLEM TO BE SOLVED: To provide a synthesis section for a transmitter capable of easily changing the number of windings of the transformer, and a digital amplitude modulation device.SOLUTION: A synthesis section for a transmitter includes: a plurality of toroidal type cores; a first support member; a second support member; and a plurality of third support members. The first support member is positioned at one side of the plurality of toroidal type cores in an axial direction of the toroidal type cores. The second support member is positioned at an opposite side to the first support member with respect to the plurality of toroidal type cores, and presses the plurality of toroidal type cores toward the first support member. The plurality of third support members are separately disposed in a circumferential direction of the plurality of toroidal type cores, and support the plurality of toroidal type cores from an outside in a radial direction of the plurality of toroidal type cores. At least one of the plurality of third support members is movable in the radial direction with respect to the first support member.SELECTED DRAWING: Figure 5
