LO Leakage to RF in mixer [hlp]

Hello Everyone;
In a design, I have used a mixer; but the LO leakage to IF section is considerable. How I can attenuate it?

what is the circuit topology of ur mixer is it Gilbert cell , or what , specify it and then e can check

khouly

You can use a diplexer which separates frequencies but provides Zo termination for all components.

Balanced or double balanced is better or if there is space ....filters

Did you use Gilbert cell for your mixer? And, what is the frequecy of your IF
and LO, if they operate in far distance on spectrum, use a simple RC low pass
filter to filter it out. (Of course, high pass filter can help if IF is higher than LO)
