Abstract: A method and apparatus for measuring a complex gain of a transmit path are disclosed. During a test mode, an IQ to radio frequency modulator modulates a quadrature RF carrier signal using a quadrature test signal. An RF to IQ down-converter down-converts a down-converter RF input signal to provide a quadrature down-converter output signal using the quadrature RF carrier signal. The down-converter RF input signal is based on the quadrature test signal and the gain of the transmit path. A digital frequency converter frequency converts the quadrature down-converter output signal, providing an averaged frequency converter output signal, which is a quadrature direct current signal representative of an amplitude of the quadrature test signal and the gain of the transmit path. Therefore, a measured gain of the transmit path is based on the amplitude of the quadrature test signal and averaged frequency converter output signal.

Abstract: The detailed description described embodiments of highly efficient power management systems configurable to simultaneously generate various output voltage levels for different components, sub-assemblies, and devices of electronic devices, sub-systems, and systems. In particular, the described embodiments include power management systems that substantially reduce or eliminate the need for inductors, large numbers of capacitors, and complex switching techniques to transform an available voltage level from a system power source, such as a battery, to more desirable power supply voltages. Some described embodiments include a charge pump that uses only two flying capacitors to simultaneously generate multiple supply outputs, where each of the multiple supply outputs may provide either the same or a different output voltage level. The described embodiments also include efficient power management systems that flexibly provide highly accurate voltage levels that are substantially insensitive to the voltage level provided by a system power source, such as a battery.

Abstract: A system and method for classifying channels in a frequency hopping wireless communication system is provided. A data collection engine operates to obtain channel metrics indicating the level of interference for each channel used by the wireless communication system. A data analysis engine operates to provide a channel map for adaptive frequency hopping (AFH) and/or a channel map for channel avoidance. More specifically, the data analysis engine first operates to filter the channel metrics to remove channel metrics indicative of frequency hopping interference. Next, the channels are divided into a number of channel blocks each including at least two adjacent channels. For each channel block, the channel metrics of the channels within the channel block are combined to provide a metric sum. The data analysis engine then operates to classify each channel as usable or unusable based on the metric sums for each of the channel blocks.

Abstract: The present invention provides a method and apparatus for estimating a multipath channel with sub-chip resolution. In general, secondary signals are characterized based on correlating a received signal including multipath signals, which include a main and the secondary signals, with a pseudo-random noise code. An inverse filter operates to increase a temporal resolution of results of the correlation of the received signal and the pseudo-random noise code, thereby allowing secondary multipath signals occurring within the same chip interval as another multipath signal to be detected and estimated correctly.

Abstract: An amplifier provides two or more selectively enabled amplifier segments allowing a source signal to be amplified with a selectable output power. A bias circuit responsive to a bias control signal enables selectable combinations of one or more amplifier segments, thus allowing selection of a desired output power. Selecting a desired output signal power via the bias control signal corresponds to selecting an overall amplifier quiescent current that decreases with decreasing output signal power. Thus, the amplifier permits a controlling system, such as a mobile terminal (e.g., cellular telephone) to amplify a transmit signal with a selectable transmit signal output power and corresponding level of amplifier quiescent power consumption. Preferably, each segment comprises one or more transistor amplification stages which, when enabled by the bias circuit, are biased to permit maximum power linear amplification for the transmit signal.

Abstract: A radio frequency (RF) system includes an RF power amplifier (PA), which uses an envelope tracking power supply voltage to provide an RF transmit signal, which has an RF envelope; and further includes an envelope tracking power supply, which provides the envelope tracking power supply voltage based on a setpoint. RF transceiver circuitry, which includes envelope control circuitry and an RF modulator is disclosed. The envelope control circuitry provides the setpoint, such that the envelope tracking power supply voltage is clipped to form clipped regions and substantially tracks the RF envelope between the clipped regions, wherein a dynamic range of the envelope tracking power supply voltage is limited. The RF modulator provides an RF input signal to the RF PA, which receives and amplifies the RF input signal to provide the RF transmit signal.
