An ultrashort-wave 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, an ultrashort-wave 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. <IMAGE> |
