摘要： A power amplifying device includes power amplifier (4) that performs power amplification, and protection circuit (6). Protection circuit (6) includes a diode having an anode side which receives an output of power amplifier (4), a capacitor having one end connected to a cathode of the diode and the other end connected to ground or power supply (3), and a resistor having one end connected to the cathode of the diode and the other end connected to the ground or power supply (3). Further, protection circuit (6) has a configuration in which a time constant obtained by the capacitor and the resistor is larger than a period of a signal output from power amplifier (4). With this configuration, it is possible to obtain a power amplifying device that can prevent damage to the power amplifier, which is caused by a high voltage generated when an antenna in an unconnected state is then connected, in a transmission state.

摘要： In a conventional configuration, it is necessary to install all radio terminals and search a route based on a fixed condition, which makes it difficult to provide a balance between an enlarged communication area and economic efficiency of a system. In a meter interface (150), a demodulator unit (156) demodulates installation information transmitted from a concentrator (100) on a regular basis, a connected target determiner unit (158) searches an upper terminal to be connected based on a threshold pre-stored in a memory unit (157), and control is executed such that when the obtained electric field intensity level is higher than a threshold, a concentrator connected with meter interfaces of a smallest number is connected to the meter interface, while when the obtained electric field intensity level is lower than the threshold, a concentrator having a highest electric field intensity level is connected to the meter interface.
