hello everyone
i need a help. i m attaching a circuit in this port. it is a 4 port mixer. can be used as a up/down conversion mixer in telemetry. i m trying to simulate this but not getting exact result. in this i m not able to understand what kind of load i should use for up and down. and why so many current sources are connected in series.

when i m trying to simulate this ckt drop across the load is very high hw can i improve this
