Regarding datasheet, VGG1-4 are gate Controls for the Amplifier. Adjust VGG1 through VGG4 to achieve the recommended bias current. However I don't see the recommended value.
Could you please give me the recommended and the max value ? The customer cannot design the power supply for the bias.
Add max value.
