Abstract
A bias circuit for supplying a bias current to an RF power amplifier by using a field-effect transistor (FET) that is controlled by a logic control signal, such as a CMOS logic control signal, for turning on or turning off the bias current supplied to the RF power amplifier, wherein the bias current will be supplied to the RF power amplifier when the FET is on, and the bias current will not be supplied to the RF power amplifier when the FET is off.
