Our customer measured the return loss of ADL5504-EVAL at RF IN : 2.4 - 2.5GHz.
The result was 4.8dB...
I think that it means VSWR = 3.71.
Is this evaluation result right? or measurement error ?
Usually, I think the VSWR is ~1.5.
D/S spec condition and the evaluation board is 75 Ω input termination resistor.
Do they need to change the value of termination resister for optimization?
Or, is there any other way?
By the way, D/S of AD8361 mentions recommended value..
