fet with 4 terminals
I have designed a mixer in which the LO is fed at the source. the simulation results are fine but the problem is the actual FET device contains 4 terminals i.e. 2 source terminals...now if i apply LO to one source terminal and ground the opposite source then the transistor blows up the moment I apply the LO..so I dnt knw wat to do with the other source terminal...I cnt change the design now so applying the LO at the gate using a combiner is not an option..any help would be appreciated..thnx
