Description
Technical Field
The present invention relates to signal combining and distributing technology, and is especially one device and method for combining and distributing carrier frequency signal.
Background
In the field of frequency division communication, it is often desirable to transmit two or more carrier frequency signals over a communication channel, such as a microwave channel. The carrier frequency signal is composed of a carrier frequency signaling and a carrier frequency receiving signal. The carrier frequency signaling is mainly composed of modulated service signaling obtained by modulating a service signal of a transmitting side onto a carrier frequency. The frequency band of carrier frequency signaling includes the frequency band of traffic signaling and guard bands for band isolation. The carrier frequency receiving signal is a carrier frequency signal sent by the opposite communication terminal. The frequency band of the carrier frequency signal includes frequency bands of carrier frequency signaling and carrier frequency receiving signals.
Fig. 1 shows a device for realizing dual carrier frequency signal combining and distributing in the existing microwave communication, in fig. 1, f1 and f1 respectively send and receive carrier frequency signaling and carrier frequency receiving signals in a carrier frequency signal f1, and so on, meaning of f2 sending and f2 receiving can be known. Viewed from the transmitting direction and the receiving direction of the device shown in fig. 1, the f1 and f2 signals pass through respective corresponding duplexers, and are combined by a combiner/distributor, and finally, the combined signals are transmitted by an antenna; signals from the antenna, including f1 receiving and f2 receiving, are distributed into two paths of signals respectively including f1 receiving and f2 receiving through the combiner/distributor, and then the two paths of signals are respectively received through the duplexer and received through f1 receiving and f2 receiving.
In microwave communication, the two-carrier frequency combiner/distributor for realizing the combination/distribution of two carrier frequency signals can be a balanced 3dB combiner and an unbalanced 6dB combiner. For a balanced 3dB combiner, the insertion loss to the combined port for one of its two split ports is about 3.8dB, and the reverse insertion loss is also 3.8 dB. For an unbalanced 6dB combiner, the insertion loss from one splitting port to the combining port is about 7dB, the insertion loss from the other splitting port to the combining port is about 2dB, and the reverse insertion losses are also 7dB and 2dB, respectively. It can be seen that the two-carrier frequency combiner/distributor introduces a small insertion loss when implementing the combining/distributing of the two carrier frequency signals.
The general communication model in communication can be summarized as the most basic point-to-point communication. Taking point-to-point wireless communication as an example, the transmission distance and the transmission capacity mainly depend on the system gain of the product. The system gain is the difference between the transmit power at one of the two ends of the communication and the receive sensitivity at the other end. The larger the system gain, the larger the transmission distance and transmission capacity of the point-to-point communication, i.e. the stronger the communication capability.
Taking the conventional microwave communication system with dual carrier frequency signal combining/distributing as shown in fig. 2 as an example, if balanced 3dB combiners are used at both ends of the communication, the insertion loss introduced by the balanced 3dB combiners may reduce the system gain of the communication system shown in fig. 2 by about 7.8 dB. In the communication system, if unbalanced 6dB combiners are adopted at two communication ends, the system gain is correspondingly reduced by about 8 dB. It can be seen that, in the communication system combining/distributing two carrier frequency signals, the existing way of combining/distributing by the combiner/distributor reduces the system gain of the communication system, thus reducing the communication capacity of the communication system, and thus reducing the transmission distance and transmission capacity. Obviously, in a communication system combining/distributing more than two carrier frequency signals, the communication capacity of the communication system is greatly reduced by the way of combining/distributing through the combiner/distributor.

In fig. 4, 1 is a first circulator, 2 is a second circulator, 3 is a third circulator, 41 is a band pass filter corresponding to the f1, 42 is a band pass filter corresponding to the f2, 11 is a first port, 12 is a second port, and 13 is a third port. In this embodiment, the second circulator and the third circulator are each a three-port circulator, the first port 11 being connected to a signal transducer such as an antenna.
In the first embodiment, the circulators are connected to each other and to the corresponding band-pass filters by cables.
The combining mechanism of the device of the present invention in the first embodiment for signaling 2 carrier frequencies is: f1 passes through the corresponding band pass filter 41 into port 22 of the second circulator 2, then passes through port 21 of the second circulator 2 into the second port 12, and finally is transmitted out through the first port 11; f2 enters the port 23 of the second circulator through the corresponding band pass filter 42, then enters the band pass filter 41 through the port 22 of the second circulator 2, and since the band pass filter 41 does not correspond to f2, i.e. the band pass filter 41 does not match with f2, f2 is bounced back to the port 22 of the second circulator 2 by the band pass filter 41, then enters the second port 12 of the first circulator 1 from the port 21 of the second circulator 2, and finally is sent out through the first port 11. Thus, the f1 and the f2 are both transmitted from the first port 11, that is, the f1 and the f2 are combined, and the f1 and the f2 are both converted into wireless signals and transmitted due to the antenna of the first port 11.
Similarly, it can be seen that the allocation mechanism of the apparatus of the present invention in the first embodiment for receiving signals of two carrier frequencies is not described herein again.

In the second embodiment, a direct-snap connection is used between the partial circulator and the corresponding band-pass filter, for example, a direct-snap connection is used between the circulator 2.2 and the corresponding band-pass filter 41. The straight-buckled connection mode saves cables between the circulators and the corresponding band-pass filters, so that the insertion loss introduced by the cables is saved, and the insertion loss of the device is further reduced.
Referring to the combining and allocating mechanism of the device of the present invention in the first embodiment, the combining and allocating mechanism of the device of the present invention in the second embodiment can be known, and details thereof are not repeated herein.
