I have a question for AD8361.
As for your "Output Intercept" on page-3 data sheet,
These ratings are guaranteed when no-signal also, correct?
Does it means same as offset voltage?
Output intercept provided on the datasheet is the y-intercept extrapolated from output transfer function of the device, when a signal is applied to the device. The output intercept is the *not* the offset voltage. The intercept values are guaranteed only when a signal is applied to the signal.
When no signal is applied to the detector, the device can exhibit offset voltages that vary from device to device, and over frequency and temperature. We don't provide any min/max limits for this parameter. If you refer to one of the newer devices such as the ADL5501, we describe this behavior in greater detail. For instance, if you take a look at page 21 on the ADL5501 datasheet, we provide a Distribution plot of the Output vs Input level for 50 devices.
Can any Analog experts answer this?
We think when there is no signal and signal,AD8361 shows same result, correct?
Thank you for your good answer.
OK, we will study with eval board or sample doing for offset changing.
As for your ADL5501,
Our frequency is 3MHz so ADL5501 is not fit for our product, I think.
But thank you for your introduce here.
