Abstract
Communications equipment including communications equipment for wireless communications may benefit from power amplifier transistors having stabilized characteristics. For example, certain power amplifier transistors may benefit from having their characteristics stabilized during bias switching. An apparatus can include a power amplifier device. The apparatus can also include a voltage or current input to the power amplifier device. An input voltage or current to the voltage or current input can be configured to be controlled according to scheduled transmission in a slot. The apparatus can also include a gate bias insertion circuit provided at the bias input. The gate bias insertion circuit can be configured to provide a reduced input voltage or current as a power amplifier bias. The reduced input voltage or current can be configured to correspond to a threshold of a transistor of the power amplifier when transmission is not scheduled in a slot.
