      … lower power RF amplifiers have a single positive supply voltage and biasing that is set by a supply referenced resistor. But most traditional GaAs and GaN amplifiers require a negative gate voltage that must be correctly sequenced to avoid damage. Active bias controllers provide a complete biasing and sequencing solution …
