i am trying to design a 2 x subharmonic upconvertor mixer.
LO=-15dbm @ 32.5 ghz
RF= -30dbm @ 25 ghz
IF = 40 Ghz
i am not getting any gain...? why ?
also i have the problem of RF feed through.. i understand it would feed through due to single balanced nature of the toplogy , but its higher power than the required IF.
lower stage is LO and upper is RF/mixer...
all the ports are properly matched
