When I want to draw a feedback system diagram in ADS2002,
I canot find a component like substractor.
I want to one signal substract the other signal,and then output

Because it is a function like reverse-coupler(it copy from one main signal),but not a coupler.
What is it in RF?
 

you need to do it in simulation just like you do it in the real world: inverse the signal (180 degree shift in phase) then add the two signals together using a 3-dB coupler.
To acheive the 180 degree you can create an s-parameter block that does not change amplitude, but changes phases by 180 degree.
 

Thank you

alternatives you can use symbolic defined devices.
