please help me
I calculated Zoe, Zoo. Then using linecalc (ADS), I calculated Width, Spacing, Length for coupled strip-line (SCLIN).
Using these values I am getting good results in Schematic. But with momemtum (Layout) I am not getting.
Then I chop all Lengths by 0.165xb (b-thickness of substrate or ground plane spacing in strip line, i taken 40mil)[G L Matthai text book]. then also i am not getting.

Of course you will not get same result with Momentum;
But if discrepancies are large, you may have e problem in your settings for Momentum.
Check the substrate definition.
Why don't you design your circuit in schematic using design guide?
- design and simulation of cross-coupled VCO using keysight ADS
- [moved] Fully Cross-Coupled Rectifier Configuration in Terms of Transistor Terminals
- Microstrip coupled lines
- Infineon BGT24MTR11 mmic: should RF in/outs be decoupled from ground?
- Coupled line filter design
- Unwanted DC voltage induced on a varactor coupled to DR? (dielectric resonator 10GHz)
