  • Patent number: 7526260
    Abstract: Apparatus, method and article of manufacture are shown for linear signal modification. An input signal is modified by providing one or more non-linear current sources and regulating at least one of the one or more current sources to output a signal based on one or more of the input signal characteristics. The modification of the output signal includes both amplification and attenuation.
    Type: Grant
    Filed: November 14, 2002
    Date of Patent: April 28, 2009
    Assignees: M/A-Com Eurotec, B.V., M/A-Com, Inc.

  • Patent number: 6891432
    Abstract: Apparatus, methods and articles of manufacture are shown for modifying electromagnetic waves. Through using various wave characteristics such as amplitude to regulate a current source, a current is output that may be used in any number of ways, such as driving an antenna or other load.

  • Patent number: 6813319
    Abstract: A transmitter for directly modulating an RF carrier with a complex baseband waveform comprises a programmable device adapted to generate amplitude and phase information collectively corresponding to a complex baseband waveform, a signal generator adapted to generate an RF carrier whose phase is responsive to phase information generated by the programmable device, a plurality of delta modulators, and an amplifier coupled to the signal generator and receiving the RF carrier with phase information. Each delta modulator is operative to sample an error signal at a time period offset from all other delta modulators to thereby generate streams of pulses collectively approximating the amplitude information. The supply voltage of the amplifier is adjusted in accordance with approximated amplitude information represented by the streams of pulses generated by the delta modulators.
