i am confused that what is the correct output wave of the quadrature mixer and how to simulate the characteristic of the quadrature mixer like the conversion gain , IP3, and so on ! thanks!
18. ### help the up_conversion mixer

i am sorry that if the LO is 4G , the IF is 20M, so tell me how to add a filter?? again, do you know what is the quadrature mixer?
19. ### help the up_conversion mixer

all the devices is ideal ,so there is no mismatch, to a quadrature mixer, so? do you know what is the quadrature mixer??
20. ### help the up_conversion mixer

when i design a quadrature up_conversion mixer the out wave of (outp－outm) is just like this who can tell me the reason?
