    Hi,

    This may be simple but please help me on some basic concepts.

    Question 1 :
    Using a 1:1 transformer (ex. http://www.minicircuits.com/pdfs/TC1-1+.pdf ), if the secondary side is terminated with 50 Ohm load. What is the input impedance looking into the primary side ? If I input a 1Vpp, 100MHz sine wave, what is the signal level at the secondary side ?

    Question 2 :
    The same as the above question, but using a 1:2 transformer (ex. http://www.minicircuits.com/pdfs/TC2-1T+.pdf ).

    Question 3 :
    The same as question 2 but secondary side terminated with 100 Ohm load.


    Thanks !
