ADMV1014 baseband DC output

Hi,

I would like to know the I/Q output voltage range using BB mode at 0Hz(DC).

I only find a peak-to-peak voltage on page 32 of datasheet, but it only shows at -25dBm RF input power excluded DC.

I want to use this value to paratice RF-to-Bits as followong document.

RF-to-Bits Solution Offers Precise Phase and Magnitude Data | Analog Devices 

I have no idea how to select a suitable ADC driver and ADC chip.

Please support me!

Thanks.

  • Hi,

    If you're referring to the baseband common mode voltage range please refer to Table 6 in the ADMV1014 datasheet. The common mode voltage can be set between 1.05 to 1.85V. There are additional bits available for DC offset error adjustment which is described in the Baseband Quadrature Demodulation Section in the Theory of Operations in the datasheet.

    Thanks,

    Taz
