    摘要: Systems and methods for power amplification using multiple digital amplifiers are provided. A power amplifier includes a first digital amplifier configured to process a digital input signal to generate a first analog output signal. The first analog output signal is configured to have a magnitude corresponding to amplitude information of the digital input signal. The power amplifier further includes a second digital amplifier configured to process an adjusted digital input signal to generate a second analog output signal. The second analog output signal is configured to have a magnitude corresponding to amplitude information of the adjusted digital input signal. An adjustment module configured to adjust amplitude information and phase information of the digital input signal generates the adjusted digital input signal. The digital input signal is adjusted to control a relationship between the first analog output signal and the second analog output signal.

    摘要: A receiver includes an antenna configured to receive a set of RF signals, and a low-noise amplifier (LNA) coupled to the antenna and amplify the set of RF signals to generate a set of amplified signals. The receiver further includes a down-conversion mixer configured to down convert the set of amplified signals to baseband frequencies. The receiver further includes a low-pass filter configured to filter from the set of amplified signals to baseband frequencies an out-of-band signal. The receiver further includes a high-pass filter configured to reverse the filtering of the low-pass filter. The receiver further includes a peak detector configured to determine whether the LNA is operating at saturation; and an automatic-gain controller configured to decrease a gain of the LNA based on the determination of the peak detector.
