    • A software defined transmit architecture includes a plurality of individually selectable components that can be selectively enabled to transmit a data signal that complies with any of a plurality of transmission standards. The software defined transmit architecture comprises components that can be enabled by associated logic to transmit, for example, communications signals that comply with the global system for mobile communications (GSM), enhanced data rates for GSM evolution (EDGE), which employs TDMA, and wide band code division multiple access (WCDMA) transmission standards. A single transmit architecture supports multiple transmission standards, thus minimizing the number of components in a multi-band, multi-mode portable transceiver, while reducing the number of active components.
    • 软件定义的传输体系结构包括多个可单独选择的组件,其可被选择性地启用以传输符合多个传输标准中的任一个的数据信号。 软件定义的发射体系结构包括可以由相关联的逻辑实现以例如发送符合全球移动通信系统(GSM)的通信信号,使用TDMA的GSM演进的增强数据速率(EDGE)的组件,以及 宽带码分多址(WCDMA)传输标准。 单传输架构支持多种传输标准,从而最大限度地减少了多频段,多模式便携式收发器中的组件数量,同时减少了活动组件的数量。

    • A mirror translation loop upconverter, that is capable of upconverting both constant envelope and non-constant envelope modulation formats, comprises a pair of phase shifters (210 and 220). The phase shifters alter the phase of the phase-modulated signal by an amount related to the amplitude of the amplitude-modulated signal. The phase shifters oppositely alter the phase of the phase-modulated signal, and therefore supply complementary phase versions of the phase-modulated signal. The phase-altered phase-modulated signals (206 and 208) from the phase shifters are then supplied to a pair of translation loops (240 and 260). The translation loops are arranged in mirror architecture so that each translation loop receives the phase-altered phase modulated signals. Each translation loop upconverts the signals and supplies a vector. The two vectors are added together to provide a signal to a power amplifier. The signal represents both the phase and amplitude information to be transmitted.
    • 能够上变频恒定包络和非恒定包络调制格式的镜像平移环上变频器包括一对移相器(210和220)。 移相器将相位调制信号的相位改变与幅度调制信号的振幅相关的量。 移相器相反地改变相位调制信号的相位,并因此提供相位调制信号的互补相位版本。 然后将来自移相器的经相位改变的相位调制信号(206和208)提供给一对平移回路(240和260)。 平移环路以镜像架构布置,使得每个平移环路接收相位改变的相位调制信号。 每个平移循环将信号上变频并提供向量。 将两个矢量相加在一起以向功率放大器提供信号。 信号表示要发送的相位和幅度信息。
