  • Publication number: 20080129386
    Abstract: An attenuation level may be set once per a command to set an average output power of output signals of a power amplifier, and outphased modulated signals may be attenuating according to the attenuation level prior to amplification of the signals by a power amplifier. An outphasing modulator may include at least a multiplier to multiply an amplitude modulation signal by a phase modulated carrier signal to generate a modulated signal. The outphasing modulator may also include a phase splitter to phase split the modulated signal to generate phase shifted modulated signals. The outphasing modulator may also include a sum-difference combiner to produce outphased modulated signals from the phase shifted modulated signals.

  • Patent number: 7088968
    Abstract: A transmitter synthesizes a signal having a phase modulated component and an amplitude modulated component. Phase and amplitude reference signals are generated from phase and amplitude information extracted from an offset output and offset input signal. An origin-offset signal source generates a compensation signal which is combined with the input and output signals to generate the offset input and output signals.

  • Patent number: 6940363
    Abstract: In a switching scheme mechanical MEMs switches are connected in parallel with solid state switches. This parallel MEMS/solid-state switch arrangement takes advantage of the fast switching speeds of the solid state switches as well advantage of the improved insertion loss and isolation characteristics of the MEMS switches. The solid-state switches only need to be energized during a ramp up/down period associated with the slower MEMs switch thus conserving power. As an additional advantage, using a solid-state switch in parallel with MEMs switches improves the transient spectrum of the system during switching operations.
