Abstract:
     The receiver includes four pieces of sum-difference (SD) receiver. Each SD receiver includes sum-coupling piece, coupling window of difference signal, two input channels, difference channel and sum channel. Input channels of the first, second SD receivers are connected to four pieces of input ends. The input channel of the third SD receiver is connected to difference channel of the first, second SD receivers. The input channel of the fourth SD receiver is connected to the sum channels of the first, second SD receivers respectively. The sum channel of the third SD receiver is connected to port of sum of pitching difference; and difference channel of it is connected to load port. The sum channel and the difference channel of fourth SD receiver are connected to port of sum channel and port of azimuth difference. The sum-coupling piece and coupling window of difference signal are located at centerline of the sum channel. Features are: excellent performance and good size.
