Temperature Coefficient of the AD8313

Using the AD8313, datasheet temperature coefficient is 'typical' 0.022dB/C.


In my circuit (measured with an opamp that follows and subtracts the offset and x6) I get an temperature coefficient of about 0,01dB/C (roughtly half the datasheet value) at 30-500MHz


I've tested a number of things and I'm quite sure it's not the conditioning circuit.


What is the expected variation of the AD8313 Could this be effected on a lot/lot basis?
