Abstract
Power amplifier having biasing with selectable bandwidth. In some embodiments, a power amplifier can include an amplifying transistor having a base for receiving a signal to be amplified, and a bias circuit configured to bias the amplifying transistor. The bias circuit can include a reference transistor having a base coupled to the base of the amplifying transistor and a collector coupled to a reference current source. The bias circuit can further include a coupling circuit that couples the collector and the base of the reference transistor. The coupling circuit can include a switchable element configured to allow the coupling circuit to be in a first state to provide a first bandwidth for the bias circuit or a second state to provide a second bandwidth for the bias circuit.
