    • 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.

    • A phase rotator (42) for a Cartesian feedback power amplifier (32) in a transmitter final stage (13) contains an integrated voltage controlled tunable resonant circuit (88) accomplishing band-pass filtering (80) at a center frequency selected by local oscillator (LO) coarse trim control signals (VVC1-4). The voltage controlled tunable resonant circuit (88) attenuates input signal harmonic levels at large fractional bandwidths for the downconverter (36) in the feedback LO path (14,15) without setting a large number of poles in the band-pass filter (80,82). The binary-weighted course trim value for controlling the gain of the LO (30) sets a bank of voltage-variable capacitors (VVC) in the voltage controlled tunable resonant circuit (88) to control the center frequency in each of two 2-pole band-pass filters (80,82), creating a composite 4-pole band-pass filter at the input of a poly-phase quadrature generation circuit (38) in the feedback LO path (14,15).
    • 在发射机最后级(13)中用于笛卡尔反馈功率放大器(32)的相位旋转器(42)包含一个集成的电压控制的可调谐谐振电路(88),其以本地振荡器选择的中心频率实现带通滤波(80) (LO)粗调控制信号(VVC1-4)。 电压可控谐振电路(88)在反馈LO路径(14,15)中衰减用于下变频器(36)的大的分数带宽的输入信号谐波电平,而不在带通滤波器(80, 82)。 用于控制LO(30)的增益的二进制加权行程修剪值在压控可调谐谐振电路(88)中设置一组电压可变电容器(VVC),以控制两个2极中的每一个中的中心频率 带通滤波器(80,82),在反相LO路径(14,15)中的多相位正交发生电路(38)的输入处产生复合4极带通滤波器。
