Abstract
A biasing circuitry is disclosed. The biasing circuitry includes a biasing module, electrically connected to a power amplifier; and a control series, having an end electrically connected to a positive voltage, and another end electrically connected to the biasing module. The control series includes a switch unit, controlled by a control voltage to be on or off; and a voltage-drop unit, connected to the switch unit in series. The voltage-drop unit is configured to adjust a bias point of the power amplifier.
