According to the datasheet of ADL5380:
The baseband outputs QHI, QLO, IHI, and ILO are fixed impedance ports. Each baseband pair has a 50 Ω differential output impedance
WHILE from the datasheet of A8366, the Differential Input Impedance of IPPA, IPMA, IPPB, IPMB pins are 217 ohm,
When ADL5380 & AD8366 were designed in AD-FMCOMMS1-EBZ board, I suppose there shall be a transformer (impedance ratio 4:1 like TC4-1W)
between, but they were connected only with a reserved lump filter replaced with 0ohm resistors in series parts.
Will this be fine?
Please advise, thanks.
