Hello, a really basic question that confuses some of us.
An RF mixer has 3 ports:
LOSC
RF
IF
In DOWN-CONVERSION:
RF is the input
IF is the output
What about in UP-CONVERSION?
Which port should be the input of the low frequency signal and which one the output of the high frequency (produced) signal?
I have found this paper **broken link removed**
which seems to connect the input to the IF for up-conversion, but I have seen on other designs the input being the RF. Does it have to do with the type of mixer?
I am basically interested in double balanced and triple balanced mixers so I would like to know how to connect these two type of mixers for up-conversion.
