摘要： A two-pin transmit/receive switch design includes a switching component configured to selectively switch in elements for a transmit signal path and elements for a receive signal path. A capacitor in the transmit signal path may be switched out when receiving signals on the receive signal path. Being able to selectively switch out the capacitor allows the capacitor value to be selected for optimal operation during transmit mode. For example, insertion loss may be minimized. In addition, elements in the receive signal path may be optimized (e.g., impedance matching) without being affected by or affecting the optimization that was performed for the transmit signal path.

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 system includes a power amplifier, a preamplifier, a first temperature sensor, and a bias generator. The power amplifier has a first gain, which is a function of a temperature of the power amplifier. The preamplifier has a second gain, amplifies an input signal, and outputs an amplified signal to the power amplifier. The first temperature sensor senses the temperature and generates a first signal. The bias generator generates a first biasing signal to bias the power amplifier, generates a second biasing signal to bias the preamplifier, and adjusts the second gain by adjusting the second biasing signal based on the first signal. The adjusted second gain compensates a change in the first gain due to the change in the temperature.
