Abstract

Abstract PURPOSE:To only pile up respective parts, which are adjusted preliminarily, to obtain a desired overall characteristics, by partitioning the inside of a casing into an upper part and a lower part with partitioning plate and partitioning the upper part into plural parts and storing function parts formed on a print board in each partition. CONSTITUTION:The inside of a casing 1 is partitioned into an upper part and a lower part with a partitioning plate 2, and the upper part is partitioned with subpartitioning plates 3 and 4, connectors 8 and 9 are fixed to a transmission part pirnt board 5 and a reception part print board 7 and are connected electrically by coaxial cables 8a and 9a. An antenna sharing equipment 10 is attached under the partitioning plate 2, and connectors 8 and 9 are connected to the sharing equipment 10, and the transmission part print board 5, a synthesizer part print board 6, and the reception part print board 7 are stored in parts partitioned with subpartitioning plates 3 and 4 and are fixed onto the partitioning plate 2 by screws or the like. The sharing equipment 10 is connected to an antenna connector 12 through a coaxial cable 11a, and an upper cover 14 is futted to the upper face of the casing 1 by fitting parts 14a and 14b, and a lower cover 15 is fitted to the lower face of the casing 1 thrugh fitting parts 15a, and thus, they are assembled. Respective parts are shielded completely by shielding members to suppress the unnecessary radiation.
