HMC1082LP4E

Hi,

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

2 ) can you suggest an opamp for the compensation network?

thank you. 

best regards

    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,
