    • The present invention concerns a circuit arrangement (1) comprising an antenna port (6), a first receiving port (3), a second receiving port (5), a first transmission port (3), a second transmission port (4),90 degree hybrids (7, 8, 9, 10, 1) being configured to transfer an input signal into two output signals that are phase shifted relative to each other, and two quadplexers (12, 13), wherein each quadplexer (12, 3) comprises a first duplexer (14) and a second duplexer (15),wherein the quadplexers (12, 13) and the 90 degree hybrids (7, 8, 9, 10, 11) are interconnected such that a leakage signal travelling from one of the transmission ports (2, 4) to one of the receiving ports (3, 5) destructively interferes at the receiving port (3, 5).
    • 本发明涉及一种电路装置(1),包括天线端口(6),第一接收端口(3),第二接收端口(5),第一传输端口(3),第二传输端口(4) 90度混合器(7,8,9,10,1)被配置为将输入信号传送到相对于彼此相移的两个输出信号,以及两个双工器(12,13),其中每个双工器(12,3) )包括第一双工器(14)和第二双工器(15),其中所述双工器(12,13)和90度混合器(7,8,9,10,11)互连,使得从一个 的发送端口(2,4)发送到接收端口(3,5)中的一个,在接收端口(3,5)上相消干涉。
