A communications apparatus includes a plurality of communications circuits and a coexistence management circuit. Each communications circuit is configured to provide wireless communications services in compliance with a protocol. The coexistence management circuit is configured to manage radio activities of the communications circuits. In response to a detection result of at least two radio activities to occur in a subsequent packet time, the coexistence management circuit is configured to determine whether an interference signal related to said at least two radio activities falls in a predetermined frequency band, and when the interference signal falls in the predetermined frequency band, the coexistence management circuit is configured to adjust a transmission power or an execution time of one of said at least two radio activities.

A calibration apparatus is used for calibrating characteristics of a power amplifier (PA) in a transmitter. The calibration apparatus includes an adaptive bias generator circuit that is used to track an envelope of an input signal received by control terminals of transistors of the PA and generate an adaptive bias voltage to the control terminals of the input transistors in response to the envelope of the input signal.
