Abstract: A mirror translation loop upconverter that is capable of upconverting both constant envelope and non-constant envelope modulation formats is disclosed. Embodiments of the invention provide the ability to upconvert a transmit signal that includes only a phase-modulated component, only an amplitude-modulated component, or both a phase-modulated component and an amplitude-modulated component. If the transmit signal includes both a phase-modulated signal component and an amplitude-modulated signal component, the phase-modulated signal component and the amplitude-modulated signal component are supplied to a pair of phase shifters. The phase shifters alter the phase of the phase-modulated signal by an amount related to the amplitude of the amplitude-modulated signal. The phase shifters oppositely alter the phase of the phase-modulated signal, and therefore supply complementary phase versions of the phase-modulated signal. The phase-altered phase-modulated signals from the phase shifters are then supplied to a pair of translation loops. The translation loops are arranged in mirror architecture so that each translation loop receives the phase-altered phase-modulated signals. Each translation loop upconverts the signals and supplies a vector. The vectors supplied by the two translation loops are constant in magnitude, and have complementary phase. The two vectors are added together to provide a signal to a power amplifier. The signal represents both the phase and amplitude information to be transmitted.

Abstract: A translation loop modulator and power amplifier in a phase and amplitude modulated transmission environment includes a translation loop having a phase locked loop and that is configured to receive a first modulated signal (PM) and that is also configured to provide a frequency specific modulated signal. The invention also includes a power amplifier configured to receive the frequency specific modulated signal, a variable gain element configured to provide a second modulated signal (AM) to the power amplifier and a switching element configured to receive a portion of an output of the translation loop and a portion of an output power of the power amplifier. The switching element is configured to apply the output portion of the translation loop to an input of the translation loop during a first time period and apply the detected output power portion of the power amplifier to the input of the translation loop during a second time period, thus allowing the phase locked loop in the translation loop to correct for any phase shift caused by the power amplifier.

Abstract: A system for a closed power control feedback loop allows for the use of a non-linear amplifier for amplifying a phase modulated (PM) signal while introducing an inverse version of the desired amplitude modulated (AM) signal into the feedback loop using a variable gain element. By introducing an inverse version of the desired AM portion of the signal into the power control feedback loop, the non-linear, and highly efficient, power amplifier may be used to amplify only the PM portion of the signal, while the AM portion is introduced by the power control feedback loop. In another aspect of the invention, an inverse version of the AM portion of the desired transmit signal is introduced into the power control feedback loop of an amplifier that is amplifying both a phase modulated signal and an amplitude modulated signal. By introducing an inverse version of the desired AM signal into the power control feedback loop, the power control feedback loop may not cancel the AM component present at the output of the power amplifier. In yet another aspect of the invention, the desired AM signal is injected into the feedback loop along with the power control reference signal.

Abstract: A system and method for minimizing power dissipation in a battery-operated mobile unit by adaptively controlling a voltage converter to provide a variable power supply voltage to a transmitter. In the preferred embodiment, the voltage converter is coupled to receive a source voltage from a battery, and is coupled to provide operating power to the transmitter or the power amplifier. The voltage converter is also coupled to receive a control signal from a controller, which adaptively activates the voltage converter to transform the source voltage to a converted voltage, or deactivates the voltage converter so as to directly apply the source voltage to the transmitter. Power dissipation is therefore minimized when conversion functions of the voltage converter are deactivated when voltage conversion is unnecessary.

Abstract: A method and apparatus for improving the sensitivity of a radio frequency (RF) receiver at certain frequencies suffering from co-channel interference. In the preferred embodiment, when a reference frequency, FREF, generates significant harmonics for a received RF signal in a selected channel, the reference frequency is varied or offset by a small amount, &Dgr;F. The harmonics of the offset reference frequency, F′REF=FREF±&Dgr;F, are thereby shifted away from the frequency of the received RF signal, thus reducing co-channel interference. The offset amount &Dgr;F is chosen such that the same injection frequency synthesized from FREF can still be synthesized from FREF±&Dgr;F by shifting N by an integer amount, preferably to N+1 or N−1. However, the invention encompasses shifting N by other integer amounts.
