Hi

 

I recently purchase a ADF4350 EVK, and I did Output A/B isolation measurement, at few GHz. When A=on, B=off, I measured ~ -15dBC leakage from B. And from above post, I think I should get 30-40 dB isolation.

 

Is that mean the EVK layout/output load is not optimized for isolation?

 

Could you please more detail guide to achieve best isolation?

 

Thanks
