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

View attachment 150716

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.
