摘要： A transceiver circuit and a method in a wireless communication network are provided, where a signal power level for a signal received at the transceiver circuit is measured and compared to a predefined threshold power level. At least two groups of power amplifiers may be used, where one group is optimized for high efficiency above the predefined threshold power level, and one group is optimized for high efficiency below the predefined threshold power level. The amplifiers may be used to amplify the received signal depending on the signal power level in relation to the predefined power threshold level.

摘要： Sets of power amplifier branches (which comprise an RF/microwave amplifier stage) are power combined within each stage and each set of power amplifier branches are biased in different classes of operation by bias circuits possessing different impedance characteristics such that the fundamental frequency components present at the output are in-phase with one another and the IMD3 components are anti-phase over a broad range of power levels. The RF input signal is provided by the output of the previous stage of the RF/microwave amplifier. The output of each stage is formed by power combining sets of these power amplifier branches, each of which are separately biased, so the fundamental components are additive resulting in the maximum possible output power and the IM3 components cancel partially or completely. IM3 reduction or cancellation can be achieved over a large range of output powers with the use of a feed forward control loop monitoring the input power and appropriately adjusting the bias currents and impedance characteristics of the bias circuits feeding the individual power amplifier branches in each stage of the RF/microwave amplifier.

摘要： A method and apparatus for dynamically adjusting the impedance between a transmitter's power amplifier (PA) and antenna to efficiently transfer power from the PA to the antenna. The impedance between the PA and the antenna is adjusted based on power level measurements and/or PA direct current (DC) consumption measurements, depending on whether the PA is a linear PA or a switch-mode PA. In another embodiment, a hybrid PA including a first stage linear PA and a second stage switch-mode PA is implemented in a transmitter. The hybrid PA selectively connects the output of the first stage linear PA to one of the input of the second stage switch-mode PA and the output of the hybrid PA, depending on the output power level of the first stage linear PA, the output power level of the hybrid PA, or a requirement indicated by a transmit power control (TPC) command.

摘要： A programmable modulator (100) is programmable to operate in either of a GMSK or 8PSK mode. When operating in a GMSK mode, a signal modulating circuit 105 receives (210) a bit stream (110), maps the bit stream (110) to a phase value in complex I, Q form and applies a progressive rotation to the phase value according to GMSK specifications. The output (140) is filtered by a filter circuit (135), preferably using a complex Finite Impulse Response (FIR) filter using the standard coefficients for an 8PSK modulation to create (215) an approximate GMSK output (165). A GMSK correction circuit (150) determines a correction term that is added to the filter circuit output (165) so as to correct amplitude variations to allow the output to conform to GSM/EDGE standards. The same modulator (100) may be programmed to operate in an 8PSK mode with linear predistortion.

摘要： The distortion compensating apparatus, which adaptively updates a distortion compensation coefficient for an amplifier based on a difference between input and output signals of the amplifier, comprises: a distortion amount detector which detects the amount of distortion of an output signal of the amplifier; a parameter holder which holds a parameter having been set therein; a parameter corrector which corrects the parameter in such a manner that the distortion amount detected by the detector is improved; a power monitor which monitors output power of the amplifier or a factor of variation in the power; and a controller which halts, if a monitoring result by the power monitor is smaller than a specified threshold value, the correction of the parameter. This arrangement makes it possible to accurately set the parameter relating to difference detection which is a factor of updating of distortion compensation coefficients of the distortion compensating apparatus.
