    • An active predistorting linearizer with agile bypass circuit for safe mode operation is used in conjunction with an amplifier. This linearizer comprises a controllable input variable-attenuator and drive-amplifier circuit supplied with the input signal to attenuate and amplify the input signal. A predistorter includes a controllable phase-shifting and amplitude-adjusting path supplied with the attenuated and amplified input signal to distort the latter signal and produce a predistorted output signal. A controllable output variable-attenuator and drive-amplifier circuit is supplied with the predistorted output signal to attenuate and amplify this predistorted output signal before supplying it to the power amplifier. A phase-shifting and amplitude-adjusting controller is connected to the controllable input variable-attenuator and drive-amplifier circuit, the controllable phase-shifting and amplitude-adjusting path, and the controllable output variable-attenuator and drive-amplifier circuit. Finally, a bypass extends in parallel with the series circuit including the serially interconnected input variable-attenuator and drive-amplifier circuit, controllable phase-shifting and amplitude-adjusting path, and output variable-attenuator and drive-amplifier circuit. This bypass defines a bypass circuit established in response to a fault condition in the series circuit to bypass the faulty series circuit.
    • 具有安全模式操作的敏捷旁路电路的有源预失真线性化调节器与放大器结合使用。 该线性化器包括可控输入可变衰减器和驱动放大器电路,该电路提供有输入信号以衰减和放大输入信号。 预失真器包括被提供有衰减和放大的输入信号的可控相移和幅度调节路径,以使后一信号失真并产生预失真的输出信号。 可控输出可变衰减器和驱动放大器电路提供预失真输出信号,以在将其提供给功率放大器之前衰减和放大该预失真输出信号。 一个移相和调幅控制器连接到可控输入可变衰减器和驱动放大器电路,可控相移和幅度调节路径以及可控输出可变衰减器和驱动放大器电路。 最后,旁路与串联电路并联延伸,包括串联的输入可变衰减器和驱动放大器电路,可控相移和幅度调节路径,以及输出可变衰减器和驱动放大器电路。 该旁路定义了一个绕串联电路故障条件建立的旁路电路,以绕过故障串联电路。

    • Disclosed herein is an LED package for a backlight unit. The LED package includes a plurality of LEDs, a die bonding part, a wire bonding part and a body. The die bonding part, on which the plurality of LEDs is arranged, allows the first electrodes of the LEDs to be electrically connected to an external circuit. The wire bonding part is spaced apart from the die bonding part by a predetermined distance to be insulated from the die bonding part and allows the second electrodes of the LEDs to be electrically connected to the external circuit so that the LEDs are operated. The body has a molding cup which is used to fill a space above the LEDs with transparent resin and a base on which the die bonding part and the wire bonding part are arranged.
