Hello,
I'm playing with J310 in source follower and i would like to know why S21 response of a such amplifier is negative, whereas in theory the power gain should be high ? Biasing is composed of two resistors, gate resistor of 1 MOhm and source resistor of 200 Ohm. Source and load impedances are 50 Ohm, load is decoupled by a capacitor.
