    • A transmission mixer (10) has a local input port (10 LO ) supplied with a local signal, an intermediate input port (10 in ) supplied with an input signal having an input frequency (f in ), a first output port (10 out1 ) for producing a first output signal having a first output frequency (f out1 ), and a second output port (10 out2 ) for producing a second output signal having a second output frequency (f out2 ). The first and the second output ports (10 out1 , 10 out2 ) are connected to first and second loads (LD1, LD2), respectively. The first load (LD1) is that where impedance-matching is made at the first output frequency (f out1 ) while the second load (LD2) is that where impedance-matching is made at the second output frequency (f out2 ).
    • 发送混合器(10)具有提供有本地信号的本地输入端口(10LO),提供有输入频率(fin)的输入信号的中间输入端口(10in),用于产生 具有第一输出频率(fout1)的第一输出信号和用于产生具有第二输出频率(fout2)的第二输出信号的第二输出端口(10out2)。 第一和第二输出端口(10out1,10out2)分别连接到第一和第二负载(LD1,LD2)。 第一负载(LD1)是在第一输出频率(fout1)进行阻抗匹配,而第二负载(LD2)是在第二输出频率(fout2)处进行阻抗匹配的负载。
