Hello all--
Say I have a mixer like the one in the attached *.wsx and I want to look at return loss on the RF, LO, and IF ports.
How do I do that?

RetLossLO = db10(hb_LargeSmix(VLO,VPORT[3],1,FreqIndexIM,[0;1]))
RetLossRF = db10(hb_LargeSmix(VRF,VPORT[1],1,FreqIndexIM,[1;0]))
where
VLO = 2*sqrt(2*dbmtow(PLO)*Z0)
VRF = 2*sqrt(2*dbmtow(PRF)*Z0),
Z0 - port impedance (50 Ohms here),
PRF, PLO - RF and LO powers, dBm
