AD9958/9 and 1:2 etc. Transformers

Dear all,

I have a AD9958 application (10-200MHz) where the output voltage swing after balun and filter could well do with a little boost. So I wondered if I could simply use a  1:2 transformer to double the voltage and thus get around an extra amplifier. Has anyone in here given this a try? This almost feels too simple to make any sense



  • Hi Matthias,

    Yes, it does introduce an amplification factor on the voltage input. If you want to attain max pow transfer, in addition to the voltage amplification, then you should settle for RL = Rs*N^2. So setting up a voltage amplification is straightforward but simultaneously achieving it with max power transfer would require a matched condition.
