VSWR : ADL5504-EVAL

Hi All.

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..

Best regards,

Hiroshi.
