Abstract: An amplifier receives an amplitude signal of a polar modulated signal at a base or gate terminal of a transistor and receives a phase modulated carrier signal of the polar modulated signal at the base or gate terminal of the transistor. The amplifier combines the amplitude signal and the phase modulated signal to produce a full complex waveform at a collector or drain terminal of the transistor.

Abstract: A method of processing an electromagnetic wave comprises regulating at least two independently controllable current sources with a signal determined from at least one characteristic of the electromagnetic wave to generate a processed electromagnetic wave from at least one of the independently controllable current sources.

Abstract: An apparatus and method for amplifying a radiofrequency signal using a main Digital to Analog Converter (RFDAC) and a subordinate Digital to Analog Converter (Sub-DAC). The main RFDAC provides a first portion of a N-bit digital output, which specifies the amplification level of the radiofrequency signal, and the sub-DAC provides a second portion of the N-bit digital word. Together, the main RFDAC and the Sub-DAC convert a complete N-bit digital word, where N specifies the resolution of the output radiofrequency signal.

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.
