Abstract: Modulation systems and methods compensate for the DC offset that is introduced by the digital-to-analog converter and/or the low pass filter thereof. Compensation is preferably provided in the digital domain, to thereby reduce DC offset within acceptable limits for the modulation that is being used. More preferably, compensation is provided by subtracting from the digital input signal, a digital value representing the DC offset in the filtered analog signal that is introduced by the digital-to-analog converter and/or the low pass filter. A sensor senses the DC offset in the filtered analog signal. An analog-to-digital converter is responsive to the sensor to convert the sensed DC offset into a digital offset signal. A subtractor is responsive to the analog-to-digital converter to subtract the digital DC offset signal from the digital input signal and to apply the digital input signal minus the DC offset signal, to the digital-to-analog converter.

Abstract: Power control circuitry for the transmitting section of a mobile terminal provides gain control for amplifiers operating at different frequencies. Preferably, one amplifier controls the signal gain the signal transmission path in the IF section and another amplifier controls gain in the signal transmission path in the radio frequency (RF) section. One variable gain amplifier may be controlled based on the strength of the received signals while the other may be controlled based on commands from the base station and/or calibration and alignment settings during manufacturing. In addition, one or both of the amplifiers may optionally be controlled in whole or in part based on calibration and/or alignment settings established during manufacturing. Preferably, the gain control signal based on received signal strength is analog based and the control signal received from the control system is a pure digital signal substantially immune to noise. In such an embodiment, the corresponding amplifier is configured to receive a digital value and provide a corresponding amplifier gain.

Abstract: A power amplifier circuit has a driver amplifier stage including a low band driver amplifier and a high band driver amplifier. A final amplifier stage includes a linear mode amplifier for amplifying digitally modulated signals and a saturated (nonlinear) mode amplifier for amplifying frequency modulated (analog) signals. A switching network interconnects the driver amplifier stage and the final amplifier stage. Depending on the desired mode of operation, an appropriate driver amplifier can be coupled to an appropriate final amplifier to most effectively and efficiently amplify analog or digital RF signals in either of a plurality of frequency bands. A diplex matching circuit is coupled to the linear mode final amplifier for impedance matching and for separating D-AMPS (800 MHz band) and PCS (1900 MHz band) digital signals. A power impedance matching circuit is coupled to the output of the saturated mode final amplifier.

Abstract: When attempting to reduce the number of battery cells in cellular telephones, a frequency synthesizer or phase locked loop located within the cellular telephone will output an increasing amount of noise. In order to reduce the amount of noise output when reducing the number of battery cells in such systems, the present invention employs a voltage step up device which effectively increases the voltage range of a voltage controlled oscillator within the frequency synthesizer. To further reduce the noise, the voltage step-up unit is employed with passive elements thus reducing the noise further and optimizing the output of the phase locked loop. Several different designs are discussed to further reduce space requirements and increase programmability of the system.

Abstract: During production, a wireless communications device manufacturer determines the version of specific integrated circuits being used by interpreting the response signals generated by the integrated circuits in response to an electronic query. The device manufacturer preferably establishes a cross reference list of response signals and computer chip versions for the affected computer chip type. Each integrated circuit chip manufacturer then designs and manufactures their respective integrated circuit chips to generate their corresponding response signal when a particular predetermined query is received by the chip. During subsequent device production, a factory system is connected to the device and sends the query signal. The computer chip detects this query and, in response, the integrated circuit generates the pre-defined response signal. The factory system compares this generated response signal to the cross-reference list of assigned response signals to determine the integrated circuit version being used. The factory system then selects the appropriate factory settings based on the integrated circuit version identified and loads those factory settings into the wireless communications device. In addition, the factory system may optionally send an activation code to the integrated circuit chip based on the version of integrated circuit chip identified to enable the additional function available on that version of integrated circuit chip.

Abstract: A narrow bandwidth signal, such as a narrowband FM signal, is modulated in a modulator that modulates a wide bandwidth signal, such as a CDMA signal, by oversampling the narrow bandwidth signal and applying the oversampled narrow bandwidth signal to the modulator. By oversampling the narrow bandwidth signal, the same fixed low pass filter can be used for both the wide bandwidth signal and the oversampled narrow bandwidth signal. Accordingly, different low pass filters or switched low pass filters are not needed.

Abstract: A dual band mobile station including a main channel synthesizer and an offset synthesizer for generating the transmit frequency and the receive intermediate frequency (IF) required for operation in each of two different bands characterized by different transmit-receive channel offsets. According to the present invention, the main channel synthesizer does not have to change its frequency when the mobile station switches between transmission and reception in either of the two bands so long as a common IF is selected for both bands, which is equal to one or the other of the channel offsets. This IF selection also allows for a reduction in the tuning range of the main channel synthesizer.

Abstract: A power controller for a mobile terminal variable gain amplifier (VGA). A controller consistent with the invention controls VGA output using a feedback error signal established based on the difference between a signal representative of the VGA output and a signal representative of a target output. The error signal causes convergence of the VGA output to the target output based on a magnitude of the difference. A method of controlling the output of a variable gain amplifier in a mobile terminal is also provided.
