More often used Galium Nitride (GaN) based Radio-Frequency high power transistors in the various RF PA configurations e.g. Doherty is by their nature easily destroyed, great care must be taken, when powering-up and shutting down this circuits. That means, proper power biasing and sequencing is necessary. The Doherty type RF PA with RF drivers four different gate, drain voltages and time when the individual voltages are turned on or off must be controled. Universal power sequencer and biasing device, which meets this requirements is described in this article.
