i am designing signle ended mixer i match if and lo ports by lumped components but rf port is not matching simultaneously so how i match three ports simultaneously.??
 

It is difficult to match such simple mixer to a reasonable optimum. This is why most good mixers are balanced, using one or more diode pairs.
 

I think he needs single ended mixer not balanced mixer! He needs to feed single ended input not differential input
 

Apparently Varuniyengar does not understand my English. One-diode mixers are almost never used as their one diode cannot be matched for all three ports. Balanced mixers can be matched well.
