Abstract: Aspects of a method and system for polar modulating QAM signals with discontinuous phase may include amplifying a signal via a plurality of amplifiers such that a combined gain of the plurality of amplifiers comprises a coarse amplitude gain and an amplitude offset gain. A gain of one or more of the plurality of amplifiers may be adjusted to set the coarse amplitude gain, and a gain of one or more remaining ones of the plurality of amplifiers may be adjusted to set the amplitude offset gain. The setting of the coarse amplitude gain and/or said amplitude offset gain may be adjusted dynamically and/or adaptively. The signal may be generated by phase-modulation of a radio-frequency carrier. The combined gain of the plurality of amplifiers may be controlled based on a desired amplitude modulation. The plurality of amplifiers may be integrated within an integrated circuit (IC) or chip.

Abstract: Double transformer balun for maximum PA (Power Amplifier) power. A novel approach is presented herein by which conversion from a differential signal to single-ended signal may be achieved using a double transformer balun design. The secondary coils of the double transformer balun also operate as a choke for the PA supply voltage. The secondary coils can operate as an RF (Radio Frequency) trap or choke to keep any AC (Alternating Current) signal components and to pass any DC (Direct Current) components. By using a double transformer balun design, relatively thinner tracks may be employed thereby ensuring a high degree of electromagnetic coupling efficiency and high performance. Also, these relatively thinner tracks consume a relatively small amount of space on the die. The double transformer balun design also includes a matching Z (impedance) block that is operable to match the Z of an antenna or line that the PA is driving.

Abstract: Methods and systems for power control with optimum power efficiency with a multi-port distributed antenna are disclosed and may include selectively enabling one or more power amplifiers (PAs) coupled to the antenna. The selective enabling may be based on a desired output power radiated from the antenna, and the PAs may be coupled to ports on the antenna based on an output impedance of the PAs and a characteristic impedance of the ports. Each of the PAs may be configured for maximum efficiency in different power ranges. The power ranges may be inversely proportional to the output impedance of the PAs. The output power may be monitored utilizing a power detector, such as an envelope detector, coupled to the antenna. The antenna may be integrated on a chip with the one or more PAs or may be located external to the chip. The antenna may include a microstrip antenna.
