摘要： An RF power amplifier module can be used without a matching device between the power amplifier module and an antenna. The power amplifier module is constructed and operated to detect, protect and maintain the performance of the power amplifier in the presence of severe VSWR load mismatches, without requiring the use of external circuitry. The RF power amplifier module includes integral detection circuitry for generating a first detection signal having a value that is indicative of the current flowing through an output power transistor and a second detection signal having a value that is indicative the voltage appearing at the output of the output power transistor, as well as integral compensation circuitry for controlling the generation of a plurality of bias current and bias voltage signals to have values that are a function of the values of the first and second detection signals, as well as the current output power level of the RF power amplifier module. Also included is an integral impedance matching circuit, coupled between the output of the output transistor and the output node,. that provides a variable impedance that is selectively controlled by an output signal from the compensation circuitry.

摘要： An equalizer operates on chip or sub-chip resolution input samples of a received spread-spectrum multipath signal to remove interference from one or more secondary propagation path signals within the multipath signal. The equalizer may be configured for cancellation of secondary signals arriving before and after a main propagation path signal, referred to as pre- and post-cursor signals, respectively. An associated communications system provides the equalizer with a path coefficient and delay value for each secondary path signal for which cancellation is desired. With its unique architechture, the equalizer cancels secondary signals displaced in time by amounts as small as the input sample time resolution or by amounts exceeding multiple chips, or even multiple symbols. The length of sample delay buffers within the equalizer, in combination with the input sample rate, determines the maximum secondary signal delay accommodated by the equalizer.

摘要： A DC-DC converter includes a variable frequency oscillator, a control system and a power train. The DC-DC converter is well suited for use in a cell phone. The control system uses the output of the oscillator to control the power train. The oscillator varies its frequency as a function of a pseudo random number generator, thereby reducing electromagnetic interference caused by ripple in the output of the DC-DC converter.

摘要： An open loop envelope tracking system calibration technique and circuitry are proposed. A radio frequency power amplifier receives a modulated signal. An envelope tracker power converter generates a modulated power amplifier supply voltage for the radio frequency power amplifier based on a control signal derived from the modulated signal. A first output power and a second output power of the radio frequency power amplifier are measured when the control signal is respectively delayed by a first delay period and a second delay period. A sensitivity of the output power of the radio frequency power amplifier is near a maximum near the first delay period and the second delay period. The first delay period and/or the second delay period are adjusted until the first output power substantially equals the second output power. The first delay period and the second delay period are used to obtain a calibrated fine tuning delay offset.

摘要： Power control circuitry is provided for controlling an output power of a transmitter of a mobile terminal operating according to a continuous time transmit scheme such as Wideband Code Division Multiple Access (WCDMA). Transmit circuitry processes a quadrature baseband signal to provide a radio frequency transmit signal. The radio frequency transmit signal is coupled to the power control circuitry via a coupler and processed to provide a feedback amplitude signal. The power control circuitry operates to remove an amplitude modulation component from the feedback signal using a reference amplitude signal generated from the quadrature baseband signal, thereby providing a measured gain signal of the transmit circuitry. Based on the measured gain signal and a target output power, the power control circuitry operates to control a gain of the transmit circuitry such that the output power of the transmit circuitry is within a predetermined range about the target output power.

摘要： A training circuit includes resources for processing magnitude and phase information received in a main propagation path signal with magnitude and phase information concurrently received in a secondary propagation path signal to determine values for magnitude, phase, and time offset of the secondary propagation path signal relative to the main propagation path signal. The training circuit can identify time offsets less than or greater than a symbol period, for either leading or lagging secondary path time offsets. A phase difference circuit, further included in the training circuit, determines a phase offset for the secondary propagation path signal relative to the main propagation path signal using main and secondary propagation path symbol phase values in combination with the time offset information. The relative magnitude, phase, and time information represents a characterization of the secondary propagation path with respect to the main propagation path.
