摘要： The present invention relates to balanced power amplifier network in combination with outphasing techniques such as Chireix. The object of the present invention is to provide a solution to the problem to combine balanced amplifiers like the current mode class D (CMCD) or class E/F with a LINC network. The main problem is that some power amplifiers have balanced output and the LINC network is single-ended so that a high power low loss transformer that works at several impedance levels is needed, which is hard to realize at cellular frequencies.

摘要： A power-amplifier arrangement (35) is disclosed. The power-amplifier arrangement (35) comprises a pulse modulator (40) adapted to receive a digital input signal of the power-amplifier arrangement (35) and generate, based on the digital input signal of the power-amplifier arrangement (35), an output signal of the pulse modulator (40) with a plurality of quantization levels. The pulse modulator has a plurality of output ports (50—1-50—n) for representing the output signal of the pulse modulator (40). Each output port (50—1-50—n) of the pulse modulator (40) is associated with a unique one of the quantization levels such that a signal output on the output port (50—1-50—n) adopts a first state when the output signal of the pulse modulator (40) equals or exceeds the associated quantization level, or, otherwise, a second state. The power-amplifier arrangement further comprises an amplifier section (55) comprising a plurality of amplifiers (60—1-60—n). Each amplifier (60—1-60—n) has an input port (65—1-65—n) operatively connected to a corresponding unique one of the output ports (50—1-50—n) of the pulse modulator (40) and an output port (70—1-70—n) for outputting an output signal of the amplifier (60—1-60—n), and a power-combining network (75) operatively connected to the output ports (70—1-70—n) of the amplifiers (60—1-60—n) and arranged to combine the output signals from the amplifiers (60—1-60—n) for generating an output signal of the power-amplifier arrangement (35).

摘要： The present invention relates to methods and devices to control and operate the functionality of a power amplifier system (100) capable of operating in at least three differential amplification modes. The drive signal's amplitude envelope controls an integrated switch network (104; 105, 106) that routes both the signal envelope and signal phase to different modulation blocks (111, 112: 109, 110: 115). Depending on the envelope strength, the operational mode of the amplifier system is possible to alter to best serve the signal statistics to provide the highest overall power efficiency.
