Abstract
PURPOSE:To realize not only a small size but a high productivity for an antenna sharing device, by unifying the both filters of the transmission and reception sides into a casing body in the same shape and using no coaxial cable for connection between the transmission and reception sides. CONSTITUTION:The antenna 21 is connected to the terminal 30 of the antenna sharing device 27 via the cable 22, and the terminal 30 is connected to the converting circuit part 31. The transmission side amplifier 25 is connected to one side of the part 31 via the transmission filter 23, and the reception side amplifier 26 is connected to the other side via the reception filter 24 each. And a converting circuit is formed at the circuit part 31 of the unit 27 so that the impedance may be opened to the reception and transmission frequency bands when the transmission and reception sides are viewed through the terminal 30 respectively. After this, the transmission and reception filters 23 and 24 are formed in a body onto a sheet of the printed circuit board containing the converting circuit. These parts are then collected into a casing body, thus realizing a small size as well as a high productivity for the device 27.
