this is AD9460 input circuit. this circuit used ADT1-1WT and 75 ohm, but our circuit use 50 ohm input signal impedance.
In the evaluation board, ETC1-1-13 with 50 ohm impedance was used, but since we use 50 ohm, 1Mhz input signal, ETC1-1-13 using 4.5 ~ 3000Mhz cannot be used.
Can the ADT1-1WT be used in a 50ohm impedance circuit as written on the evaluation board DataSheet?
Also we need a splitter that inverts the signal by 0 and 180 degrees before input to the ad9460. Are there any ICs that AnalogDevice recommends?
