When I designed my first microwave pre-amplifier, I noticed that my bias point was totally off. I used the typical characteristic curves shown on the datasheet (for an ATF-55143 pHEMT) and based those curves for my design, which I believe was not the best way to calculate my bias network resistors. If I was to design another microwave pre-amplifier, would you think I should test the characteristic curve for my transistor before calculating resistor values?
