Re: Bias current problems

The gate bias for IRF510 60-mA is a good point to work in class AB to balance amplification linearity and power consumption. From my observation, if it is too small, the RF output will be a bit negatively affected. In your senario, if you increase from 50-mA to 60-mA, probably you can get a bit more output but don't set it any bigger.

Question for Adam:


How does the IRF510's gate bias current affect transmit power?

Thank you,
