Product Number: AD8338
I am using AD8338 in VGA Mode. The given input is 10 kHz - 300 kHz, -40 dBm. Operating this circuit on DC 4.7V. When the Gain voltage is set to 0.8V, there is no output. The output came only after reducing the Gain voltage nearly 0.6V, which gives less than our desired gain, i.e., 60
What changes should be made to the schematic/PCB to achieve a Gain of 60 with an appropriate output?
Attached are the spectrum plot, the implemented schematic, and the fabricated PCB.
