Input impedance matching of ADL5335


My customer is designing a wideband transmitter with AD9172 & ADL5335.

Analog ouput impedance of AD9172 is 'Differential Impedanc 100Ω' in AD9172 datasheet.

Input impedance of ADL5335 is 'Differential input drive 50Ω' in ADL5335 datasheet.

In this case, should the customer use a 2:1 balun to connect the two devices without loss ?

Thanks a lot.
