本発明はマイクロ波を用いた双方向の信号伝送における
中継装置に関し、特にマイクロ波信号を増幅して中継す
るマイクロ波中継装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a repeater for bidirectional signal transmission using microwaves, and particularly to a microwave repeater that amplifies and relays microwave signals.
一般に双方向の信号伝送を行うマイクロ波中継装置では

備の２台の増幅器で構成し、現用増幅器が故障した際に
は予備増幅器を動作させて中継を確保している。Generally, a microwave repeater that performs bidirectional signal transmission is provided with amplifiers for uplink and downlink, respectively. As a relief measure when the amplifier for each line breaks down, conventionally the amplifier for each line is configured with two amplifiers, one for the current use and one for the backup, and when the active amplifier fails, the backup amplifier is activated. We are ensuring relay coverage.

There is a problem in that this requires multiple amplifiers, making the entire microwave repeater expensive. Furthermore, since these spare amplifiers are normally provided in a state where the power is always turned on, that is, in a hot standby state, there is also the problem that the power consumption of the microwave relay device increases.

A first transmitting/receiving duplexer 3 and a second transmitting/receiving duplexer 4 are connected to the downlink shared transmitting/receiving antenna 2, respectively. These duplexers 3 and 4 each consist of a circulator 3a4a and a pair of bandpass filters 3b, 3c and 4b, 4c whose center frequencies are set to the uplink frequency and the downlink frequency, respectively. Signals of different frequencies are passed in opposite directions. Therefore, a downlink and an uplink are arranged in parallel between the duplexers 3 and 4, and the downlink includes a first microwave broadband amplifier 7 and each circulator 5 on the input side and the output side. 9 is connected. Similarly, a second microwave broadband amplifier 8 and circulators 6 and 10 on the input and output sides are connected to the uplink. Furthermore, the input circulators 5.6 are interconnected here, and the output circulators 9.10 are similarly interconnected.

ンテナ２より送信される。The signal f2 received by the upstream transmitting/receiving antenna 1 is input to the first transmitting/receiving duplexer 3, and is passed through a circulator 3a and a bandpass filter 3b set to the center frequency f2. The signal is then input to the first microwave broadband amplifier 7 through the input circulator 5, where it is amplified to a required level. The amplified signal passes through the output side circulator 9 and is input to the second duplexer 4, where it passes through the bandpass filter 4c set to the center frequency f2 and the circulator 4a. Thereafter, it is transmitted from the downlink shared antenna 2.

After passing through the input side circulator 5, it is amplified to the required level by the first microwave broadband amplifier 8.The amplified signal is passed through the output side circulator 10.
The signal is input to the first duplexer 4 through the transmitter/receiver, where it passes through the bandpass filter 3c set to the center frequency fI and the circulator 3a, and is transmitted from the uplink antenna 1.

The downlink frequency signal f2 that has passed through the uplink transmitting/receiving antenna 1 and the first transmitting/receiving duplexer 3 and reaches the second microwave broadband amplifier 7 is reflected at its input end because the amplifier 7 is out of order. and returned to the circulator 5. From here, the uplink circulator 6
and are commonly amplified by a second microwave broadband amplifier 8 via a circulator 6. Furthermore, after passing through the output side circuit I/-10, it goes to the first duplexer 3, but here, if a frequency signal other than f1 is received, it is reflected, so it is returned to the ceculator 10 again, and from there, it is reflected. Directed to circulator 9. After passing through the transmitter 9, the signal reaches the second transmitter/receiver 4, and is transmitted from the transmitter/receiver antenna 2 in the downstream direction.
