FIG. 1 is a configuration diagram showing an active array antenna device according to Embodiment 1 of the present invention, and also shows an active array antenna device for transmission. In the figure, reference numeral 1 denotes a plurality of element antennas arranged along a planar or parabolic or other curved antenna opening surface, and 2 is connected to each of these element antennas 1 and transmitted. These are a plurality of amplifiers that perform high-frequency power amplification. Reference numeral 3 denotes a power divider that distributes a high-frequency signal input to the amplifier 2, and 4 denotes a transmitter that generates a high-frequency signal to be transmitted and sends the signal to the power divider 3. Reference numeral 5 denotes an amplifier driving DC power supply for supplying power to each of the amplifiers 2 for driving them. The output voltage when power is supplied from the amplifier driving DC power supply 5 to the amplifier 2 is equal to the driving voltage of the amplifier 2. The value is set higher than the voltage. Numeral 6 is provided between the amplifier driving DC power supply 5 and the amplifier 2 in correspondence with each of the amplifiers 2, and outputs an output voltage when power is supplied from the amplifier driving DC power supply 5 to the amplifier 2.
This is a DC / DC converter as an amplifier voltage adjusting mechanism for reducing the driving voltage of the amplifier 2.

Next, the operation will be described. The transmitter 4 generates a high-frequency signal to be transmitted, and this high-frequency signal is distributed by the power distributor 3 and input to each amplifier 2. Each of the amplifiers 2 is driven by being supplied with power from an amplifier driving DC power supply 5 and amplifies the high frequency signal distributed by the power distributor 3. The high-frequency signals amplified by these amplifiers 2 are sent to the respective element antennas 1 to which they are connected. Each element antenna 1 is arranged along a flat or parabolic or other curved antenna opening surface, and radiates a high-frequency signal transmitted from the transmitter 4 and amplified by the amplifier 2 into space as a radio wave. I do.

Here, when power for driving each amplifier 2 is supplied, the amplifier driving DC power supply 5 sets its output voltage to a value higher than the driving voltage of the amplifier 2 as described above. The signal is output to a transmission line between the amplifier driving DC power supply 5 and the DC / DC converter 6. When the DC / DC converter 6 receives the power supplied to the amplifier 2 from the amplifier driving DC power source 5, the DC / DC converter 6
Is supplied to each of the amplifiers 2 after the pressure is reduced to the drive voltage. Therefore, when the same power is supplied from the amplifier driving DC power supply 5 to each amplifier 2, the value of the current flowing through the transmission line from the amplifier driving DC power supply 5 to each DC / DC converter 6 is The output voltage of the power supplied from the power supply 5 to each amplifier 2 is smaller than the output voltage of the drive voltage of the amplifier 2.

As described above, according to the first embodiment, the power supplied to the amplifier 2 is transmitted at a voltage higher than the drive voltage of the amplifier 2, so that the power transmission is performed at the drive voltage of the amplifier 2. Since the current flowing through the transmission line can be reduced as compared with the conventional active array antenna device, and the conductor loss due to the current flowing through the transmission line can be reduced, an active array antenna device with reduced power transmission loss can be provided. The effect that it can be realized is obtained. In particular, when the transmission distance from the amplifier driving DC power supply 5 to the amplifier 2 is long, the effect that power transmission loss can be significantly reduced compared to the conventional active array antenna device is obtained.

Embodiment 2 FIG. 2 is a configuration diagram of an active array antenna device according to a second embodiment of the present invention.
