FIELD: physics.
SUBSTANCE: in the device for identification on surface acoustic waves (SAW), containing a case, transceiver antenna, acoustic transmission line on whose working surface is placed a receiver-transmitting inter-digital transducer, connected with the antenna and deflector of SAW, are gathered N parallel acoustic channels, in each of which apart from SAW deflectors are placed one after another multi-stripline directional couplers, overlapping two adjacent acoustic channels and transferring SAW from one acoustic channel to another, but in the opposite to the incoming SAW direction, moreover the number of couplers is one less than the number of acoustic channels, and the receiving-transmitting inter-digital transducer is made unidirectional with the internal reflector and is placed in the first acoustic channel.
EFFECT: increase in mechanical stability.
