    摘要: A transmitter circuit (10) includes a phase shifter (20) that receives phase shift compensation and timing data (40), and an amplifier (30) that receives a control signal (70) to initiate an efficiency enhancement technique. The phase shifter (20) receives the phase shift compensation and timing data (40), and the amplifier (30) receives the control signal (70) at a pre-defined relative time such that the compensation phase shift by the phase shifter (20) compensates for a pre-determined phase change in the amplifier (30) to produce an RF output signal (80) with a reduced predicted phase change.

    摘要: An apparatus and method for dual mode power control. A transmitter is capable of operating in a first mode of operation and a second mode of operation, the first mode of operation and the second mode of operation including a closed loop control mode and an open loop control mode, the first mode of operation being different from the second mode of operation. The transmitter can be operated in the first mode of operation. A transmitter output power characteristic of the first mode of operation can be read back. The transmitter output power characteristic of the first mode of operation can be correlated to a transmitter output power characteristic of the second mode of operation. The first mode of operation can be switched to the second mode of operation based on the transmitter output power characteristic of the second mode of operation.
