Used the same schematics as the datasheet with since wave input , no output
Hi SANTONY ,
Good day. Some connections were not aligned with Figure 26 of the datasheet, the frequency doubler. For example, the R2 resistor in the datasheet is across X1 and X2, while your schematic shows X2 and Y2 connected with a 1.6k resistor (this should be connected directly).

Thank you Gladion for the reply, But the LTSIM works the way it was shown in my schematics but not while breadboarding as well as on the proto board. I will try with your recommendation and let you know
