<p>PURPOSE:To attain low power consumption and miniaturization and light weight by simplifying the constitution of a reception signal converter by employing a system by which an output signal from the reception signal converter is transmitted in analog fashion as an intermediate frequency signal is. CONSTITUTION:Signals in which a transmission signal and a local oscillation signal become time division signals inputted from an external device to an input terminal 12 are inputted to respective reception signal converter 4 by a distributor 5. The transmission signal outputted from the reception signal converter 4-1 is inputted to a feed circuit 3-1, and the transmission signal is divided, then, divided signals are inputted to plural small transmitter/receivers 2-1a to 2-1m connected to the feed circuit 3-1. The transmission phase of the transmission signal is controlled by a phase shifter 13, and the signal is amplified by an amplifier 15, and after that, it is radiated to a space via element antennas 1-1a to 1-1m. Thus, the circuit configuration of the reception signal converter 4 can be simplified, and the transmission system of the reception signal converter 4 with a signal processor or the external device can be improved. In such a way, it is possible to attain the miniaturization, the light weight, and the low power consumption as a whole.</p> |
