Patent number: 6711389Abstract: 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.Type: GrantFiled: February 16, 2001Date of Patent: March 23, 2004Assignee: Telefonaktiebolaget L.M.

Patent number: 6556545Abstract: An RF full-duplex communication device operates in a selected range of channels spaced by a selected increment. A transmitter and a receiver are connected to a duplex filter for simultaneously transmitting and receiving signals. A low frequency offset channel stepper is adapted to selectively shift frequency either the designated duplex spacing or offset therefrom. A high frequency channel stepper is connected to the transmitter and selectively connected to the receiver either directly or through the low frequency offset channel stepper, where the high frequency channel stepper is adapted to selectively shift frequency in steps substantially equal to the selected increment.Type: GrantFiled: December 21, 1999Date of Patent: April 29, 2003Assignee: Ericsson Inc.Inventor: Ronald D.

Patent number: 6535561Abstract: 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. The DC offset that is introduced by the digital-to-analog converter and/or the low pass filter of the modulator is compensated, preferably 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 sampled 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.Type: GrantFiled: September 11, 1998Date of Patent: March 18, 2003Assignee: Ericsson Inc.Inventors: Ronald D.

Patent number: 6438382Abstract: A mobile terminal uses stored GPS data to expedite position determination when placing emergency calls. The mobile terminal receives supporting GPS data such as almanac and ephemeris information from a supporting digital wireless network when digital service is available. When operating in an analog service area where GPS data is not available from the analog wireless network, the mobile terminal uses GPS data previously received in a digital service area, unless that data is too old to be useful. Additionally, the mobile terminal can periodically update its stored GPS data while in standby in an analog service area, based on receiving the needed data directly from available GPS satellites. The mobile terminal or digital wireless network may automatically update GPS data stored in the mobile terminal based on the age of stored data, or based on the probability of moving into an analog service area.Type: GrantFiled: February 14, 2001Date of Patent: August 20, 2002Assignee: Telefonaktiebolaget LM Ericsson (Publ.)Inventors: Ronald D.

Patent number: 6370203Abstract: 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.Type: GrantFiled: November 4, 1998Date of Patent: April 9, 2002Assignee: Ericsson Inc.Inventors: Ronald D.

Patent number: 6298244Abstract: 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.Type: GrantFiled: June 10, 1998Date of Patent: October 2, 2001Assignee: Ericsson Inc.Inventors: Ronald D.

Patent number: 6253076Abstract: 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.Type: GrantFiled: February 25, 1999Date of Patent: June 26, 2001Assignee: Ericsson Inc.Inventor: Ronald D.

Patent number: 6157821Abstract: 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.Type: GrantFiled: October 23, 1997Date of Patent: December 5, 2000Assignee: Ericsson Inc.Inventors: Ronald D.
