摘要： An advanced balanced RF power amplifier circuit is provided The RF power amplifier has a pair of RF amplification paths (19,21) constructed to efficiently operate in a high-power mode. When instructed to operate in a low-power mode, one of the amplification paths (21) is deactivated, and optionally, an impedance device (53) is also set to operate at a low-power impedance value. With only path (19) operating in low-power mode, the network RF topology has changed from the topology of the high-power mode. This new topology provides increased impedance on the active RF amplification path as compared to when both RF amplification paths were active. This increased impedance causes the RF power amplifier to operate more efficiently in its low-power mode. Depending on the specific application and target performance, the impedance may be sufficiently increased simply by deactivating one of the RF amplification paths, and in other cases it may be desirable to switch an active or passive impedance device to operate at a low-power impedance. The impedance device enables further adjustment and tuning of the impednace in the low-power topology.
摘要翻译：提供了一种先进的平衡RF功率放大器电路RF功率放大器具有一对RF放大路径（19,21），其被构造为有效地以高功率模式工作。当被指示以低功率模式工作时，放大路径（21）中的一个被去激活，并且可选地，阻抗装置（53）也被设置为以低功率阻抗值工作。只有路径（19）在低功耗模式下工作，网络RF拓扑已从高功率模式的拓扑变化。与两个RF放大路径都有效时相比，这种新的拓扑结构在有源RF放大路径上提供增加的阻抗。这种增加的阻抗使得RF功率放大器在其低功率模式下更有效地操作。根据具体的应用和目标性能，可以简单地通过去激活RF放大路径中的一个来充分地增加阻抗，并且在其他情况下，可能期望将有源或无源阻抗器件切换为以低功率阻抗工作。阻抗器件能够进一步调整和调整低功耗拓扑中的阻抗。

摘要： According to an exemplary embodiment, an amplification module (200) includes a bias circuit (204) coupled to an input of an amplifier (202), where the bias circuit (204) is configured to charge the input of the amplifier (202) to a final bias voltage. The amplification module (200) further includes a fast charge circuit (210) configured to provide a low impedance path (246) between the bias circuit (204) and the input of the amplifier (202) when a voltage at the input of the amplifier (202) is less than the final bias voltage, thereby reducing an enable time of the amplifier (202). The fast charge circuit (210) is further configured to open the low impedance path (246) when the voltage at the input of the amplifier (202) is substantially equal to the final bias voltage. The fast charge circuit (210) includes a comparator (224) configured to cause the low impedance path (246) to open when the voltage at the input of the amplifier (202) is substantially equal to a reference voltage.

摘要： A method and apparatus for linear amplification of a modulated carrier signal or multi-carrier signal is disclosed. The linearity of the amplifier is improved by employing dynamic load line adjustments. A second current source coupled to the amplifier output load is turned on just before the amplifier reaches a nonlinear regime and reduces the effective load to prevent the amplifier allowing sufficient power to reach the nonlinear regime near saturation. The technique is particularly advantageous for amplification of a signal with large peak to average ratio.

摘要： The present invention teaches a variety of driver amplifiers (300) having a transmit mode suitable for driving the load resistance (Rload) of a network with an amplified version of the input signal (Vin), and a standby mode wherein the driver amplifier (300) consumes substantially no current and isolates the load resistance (Rload) from the input signal (Vin). These amplifiers (300) are also characterized in that during transitions back and forth between standby mode and transmit mode, a minimum of standby transient leaks out onto the network. Further, the noise power delivered to the network in standby mode is substantially minimized, the remaining noise being primarily due to thermal noise produced by a resistor (R1) utilized to provide matched termination to the network.
摘要翻译：本发明教导了具有适于驱动具有放大版本的输入信号（Vin）的网络的负载电阻（Rload）的发射模式的各种驱动放大器（300），以及待机模式，其中驱动放大器（300 ）消耗基本上没有电流，并从输入信号（Vin）隔离负载电阻（Rload）。这些放大器（300）的特征还在于，在待机模式和发射模式之间来回转换的过程中，待机瞬变的最小值泄漏到网络上。此外，在待机模式下传送到网络的噪声功率基本上最小化，剩余噪声主要是由于用于提供与网络的匹配终端的电阻器（R1）产生的热噪声。
