摘要： The present disclosure relates to de-multiplexing at least one RF input signal feeding RF power amplifier circuitry to create multiple de-multiplexed RF output signals, which may be used to provide RF transmit signals in an RF communications system. Output transformer circuitry is coupled to outputs from the RF power amplifier circuitry to provide the de-multiplexed RF output signals, which may support multiple modes, multiple frequency bands, or both. The de-multiplexed RF output signals may be used in place of RF switching elements in certain embodiments. As a result, RF front-end switching circuitry in the RF communications system may be simplified, thereby reducing insertion losses, reducing costs, reducing size, or any combination thereof. Additionally, the output transformer circuitry may provide load line transformation, output transistor biasing, or both to the RF power amplifier circuitry.

摘要： Radio frequency (RF) transmitter circuitry, which includes an envelope tracking power supply and an RF power amplifier (PA), is disclosed. The RF PA operates in either a first operating mode or a second operating mode, such that selection of the operating mode is based on compression tolerance criteria. During the first operating mode, the RF PA receives and amplifies an RF input signal using a first compression level. During the second operating mode, the RF PA receives and amplifies the RF input signal using a second compression level, which is greater than the first compression level. The envelope tracking power supply provides an envelope power supply signal to the RF PA. The envelope power supply signal provides power for amplification.

摘要： A method of defining a quasi iso-gain supply voltage function for an envelope tracking system is disclosed. The method includes a step of capturing iso-gain supply voltage values versus power values for a device under test (DUT). Other steps involve locating a minimum iso-gain supply voltage value, and then replacing the iso-gain supply voltage values with the minimum iso-gain supply voltage value for corresponding output power values that are less than an output power value corresponding to the minimum iso-gain supply voltage value. The method further includes a step of generating a look-up table (LUT) of iso-gain supply voltage values as a function of input power for the DUT after the step of replacing the iso-gain supply voltage values with the minimum iso-gain supply voltage value for corresponding output power values that are less than an output power value corresponding to the minimum iso-gain supply voltage value.

摘要： Embodiments of the present disclosure relate to a multi-mode RF system, which is capable of transmitting and receiving RF signals using any of multiple RF communications bands. The multi-mode RF system may integrate RF band specific bandpass filters and low noise amplifiers (LNAs) into a single front-end module, such that each filter and amplifier pair provide selection and gain for at least one RF communications band. Outputs of the LNAs may be combined to provide one or more common signals to a transceiver module, which processes baseband signals associated with the RF communications bands. By integrating the filters and amplifiers into a single module, the filters and amplifiers may be closely coupled to one another, thereby supporting short signal paths between the filters and amplifiers, and having impedances high enough to provide good filter selectivity.
