Abstract
PURPOSE: To simplify the circuit constitution by securing separation between the transmission and reception waves without using the transmission/reception branching filter, switching the phase- shift switch and then carrying out the switching for the turning direction of the same turning circular polarized wave transmission/reception or the switching of 90 for the polarized wave direction of the linear polarized wave transmission/reception.
CONSTITUTION: The transmission signal sent from transmitter 1 connected to terminal 10 is supplied to hybrid 4 and then delivered to terminals 11 and 12 in the form of the orthogonal polarized wave. And the reception signals supplied to terminals 11 and 12 are supplied to receiver 2 connected to terminal 13 in the form of the orthogonal polarized wave. Then terminals 11 and 12 are connected together via input and output terminals 15 and 16 of cross dipole antenna 6 plus the transmission circuit, and phase-shift switch 20 is inserted to either one side of the transmission circuit. Thus the switching is carried out to short-circuit unit 21 via the control signal sent from control signal input terminal 30 of switch 20, and then the electric length of the transmission line to the frequency of the transmission and reception each is switched to the electric length identical to the transmission line of the other side and the electric length having a 180 shift to the transmission line each. Thus the constitution is simplified for the branching filter.
