Patent number: 7660598Abstract: A wireless device is equipped with multiple (e.g., two) antennas, which may be of different designs. Each antenna interacts with the wireless environment in a different manner and achieves different scattering effect. The wireless device has one transmit signal path for each antenna. Each transmit signal path generates an RF output signal for transmission from the associated antenna. The wireless device controls the operation of one or more transmit signal paths to achieve a larger received signal level at a receiving base station. The wireless device may (1) autonomously adjust the transmit signal path(s) without relying on any feedback from the base station or (2) adjust the transmit signal path(s) based on transmit power control (TPC) commands received from the base station. The wireless device may selectively enable and disable each transmit signal path, vary the phase and/or gain of each transmit signal path, and so on.Type: GrantFiled: December 21, 2004Date of Patent: February 9, 2010Assignee: QUALCOMM, IncorporatedInventors: Kenneth Charles Barnett, Charles J. Persico, Paul Peterzell

Publication number: 20080014895Abstract: A direct downconversion receiver architecture having a DC loop to remove DC offset from the signal components, a digital variable gain amplifier (DVGA) to provide a range of gains, an automatic gain control (AGC) loop to provide gain control for the DVGA and RF/analog circuitry, and a serial bus interface (SBI) unit to provide controls for the RF/analog circuitry via a serial bus. The DVGA may be advantageously designed and located as described herein. The operating mode of the VGA loop may be selected based on the operating mode of the DC loop, since these two loops interact with one another. The duration of time the DC loop is operated in an acquisition mode may be selected to be inversely proportional to the DC loop bandwidth in the acquisition mode. The controls for some or all of the RF/analog circuitry may be provided via the serial bus.Type: ApplicationFiled: September 27, 2007Publication date: January 17, 2008Applicant: QUALCOMM INCORPORATEDInventors: Tao Li, Christian Holenstein, Inyup Kang, Brett Walker, Paul Peterzell, Raghu Challa, Matthew Severson, Arun Raghupathy, Gilbert Sih

Publication number: 20050156662Abstract: Methods and apparatus for amplifier AM and PM predistortion and autocalibration. AM and PM amplifier distortion can be corrected using predistortion. The AM and PM distortion characteristics of the amplifier are determined using an autocalibration technique. The amplifier characteristics can be stored in distinct look up tables. Alternatively, the inverse of the amplifier characteristics can be stored in distinct look up tables. Signals that are to be amplified are characterized in polar format having a phase component with a normalized magnitude and a magnitude component. The phase component can be predistorted by applying the inverse of the PM distortion characteristics to the signal. Similarly, the magnitude component can be predistorted by applying the inverse of the AM distortion characteristics to the signal. The predistorted phase component can be amplified using the previously characterized amplifier.Type: ApplicationFiled: November 12, 2004Publication date: July 21, 2005Inventors: Arun Raghupathy, Puay See, Gurkanwal Sahota, Robert Reeves, Paul Peterzell

Patent number: 6816711Abstract: An antenna sharing system and method. In the illustrative embodiment, the inventive system includes a first matching network coupled to a first circuit; a second matching network coupled to a second circuit; and a switch having a first throw coupled to the first network, a second throw coupled to the second network, and a pole coupled to the antenna. In the specific implementation, the first circuit is a cellular subsystem and the second circuit is a Global Positioning System subsystem. The system further includes a controller for selectively actuating the switch whereby the first network is coupled to the antenna in a first operational mode and the second network is coupled to the antenna in a second operational mode. In the illustrative implementation, the first network provides an impedance match to the switch and the antenna with respect to the first circuit. The second network provides an impedance match to the switch and the antenna with respect to the second circuit.Type: GrantFiled: November 27, 2001Date of Patent: November 9, 2004Assignee: Qualcomm IncorporatedInventors: Randolph Standke, Paul Peterzell

Patent number: 6374116Abstract: A method of adjusting transmit power in a CDMA portable phone to maintain adjacent channel power rejection (ACPR) passing margin includes the steps of amplifying a first radio frequency (RF) signal according to a first gain to produce a second RF signal, and amplifying the second RF signal according to a second gain to produce a third RF signal. A desired power level of the third RF signal is determined and a new gain value is computed from the desired power level. The first gain value is adjusted to the new value. A system for adjusting transmit power in a CDMA portable phone to maintain adjacent channel power rejection (ACPR) passing margin includes an automatic gain control (AGC) amplifier having an AGC input terminal, an AGC output terminal, and a control signal input terminal. The system also includes a power amplifier (PA) having a PA input terminal and a PA output terminal, wherein the PA input terminal is connected to the AGC output terminal.Type: GrantFiled: September 22, 1999Date of Patent: April 16, 2002Assignee: Qualcomm IncorporatedInventors: Paul Peterzell, Sheikh A.
