It's hard to say which coupler is "best" for your application.
I would use either the
CouplerSingle
or
S3P_Eqn
The CouplerSingle is modeled after a real physical coupler with loss/directivety etc. If you just want to ideally induce a signal into your circuit then you could use the S3P_Eqn, where you can define the coupling as ideal by setting the coefficients S11, S12, S13... to 0 and 1's.
