Description
Technical field
This utility model relates to electronic engineering field, is specifically related to a kind of synchronizing signal backboard.
Background technology
Radio wave is all by certain coded treatment to reach certain effect by traditional radar or communication technology. Such as radar utilizes coding techniques to improve spatial resolution and to strengthen electronic warfare capability, and communication system utilizes coding techniques to improve the capacity of channel. But it is as technical development, just cannot continue to improve the performance of radar or communication system by coding techniques. Radar is in order to continue improve its spatial resolution and strengthen electronic warfare capability, it is proposed that utilizes multiple transmitting and accepts passage to deduce the radar signal propagation path in space, thus improving resolution. Communication system, in order to hold more communication channel simultaneously, also requires that and utilizes multiple transmitting and accept passage to improve the channel carrying capacity of base station and to eliminate multipath effect, and the multipath effect between building is further cut down. So radar can allow multiple transmitting and accept the ability that passage works with the system that is desirable that communicates simultaneously.
One of them key that multiple transmitting reception passages work simultaneously needs several digital to analog converters (DAC)/analog-digital converter (ADC) is operated simultaneously exactly. Wherein digital to analog converter is responsible for transmitting terminal and receiving terminal is responsible for by analog-digital converter. One key request of this operation is exactly multiple digital to analog converter or multiple analog-digital converter must operate at below same clock frequency, otherwise the multichannel ability of system not only can not play, and likely interferes with each other between channel all the better and causes that system cannot be run. So people generally adopt coaxial cable then to adopt optical fiber or coaxial cable to transmit to the synchronizing signal transmitting low frequency to the data signal controlling digital to analog converter or the frequency of analog-digital converter clock chip, digital to analog converter or analog-digital converter on engineering. Between coaxial cable, the concordance of length is to ensure that synchronizing signal can arrive a key index of clock chip simultaneously. Yet with the problem of production technology, the concordance of coaxial cable cannot ensure well, so low frequency (1 megahertz or following) synchronizing signal can only be used to reduce the synchronizing signal sensitivity to cable sample different in size. The problem so brought is exactly that synchronous signal frequency is low, and the effect of synchronization is bad. The cable optic fibre being exactly too much is also had to be easy to installing or wrong in the middle of the process of maintenance, thus affecting installation and the maintenance of the complete machine of radar or communication system.
