HMC1082LP4E

Hi DNGZK,

1). Is the HMC1082LP4E Gain vs Temperature performance data given in the datasheet  obtained with the temperature compensation network ?

There is no on chip compensation network for gain vs. temp.

The Vdet and Vref pins are a separate power detector circuit that has no impact on the gain levels. It is used to have a DC voltage measurement track the RF output power of the circuit. Yes, these can be left open if not used.

2). Can you suggest an opamp for the temp compensation network?

I would suggest the AD8531 or AD8541.

Thanks,

DanO
