Bias circuit for a radio frequency power-amplifier and method therefor |
摘要 |
A wireless communication unit comprises a transmitter having a power amplifier biased by a bias circuit and a controller operably coupled to the bias circuit for setting one or more bias levels of the power amplifier. The bias circuit is a single bias circuit and is configured to provide either a current mode bias control of the power amplifier or a voltage mode bias control of the power amplifier in response to a control signal from the controller. In this manner, a single bias control circuit can be used to support applications that benefit from both current mode bias control and voltage mode bias control of the power amplifier. |
