    Working of AD8367 evaluation Board

    Hello All,

    Have anyone used AD8367 evaluation board? I have bought it & I am try to understand its working.
    What will be the output level of it when It is in VGA mode, also following are the settings done and input that I have given-
    SW-1 -> A
    SW-2 -> A
    Voltage -> 5V
    V(GAIN) -> 50mV
    INPUT ->
    Frequency= 75 MHz, Level= -40dBm


    Thanks & Regards,
    Pravin.

    Hi,

    you urgently need to read the datasheet.

    VGA_Mode:
    MODE pin (controlled by SW-2) = VP = 5V
    DETO pin (controlled by SW-1) = V_Gain = 50mV

    Thus - as far as I can see - the gain should be about -3dB

    Thanks,

    Exact result of about -3 dBm I was expecting, but instead of this I am getting -21 dBm. Also in AGC mode, constant level that I am getting is -14 dBm.
