| 20120243579 | System and Method for Tuning an Antenna In a Wireless Communication Device - In accordance with some embodiments of the present disclosure, a control path for a wireless communication device may include a radio frequency coupler having a coupled port and a terminated port, the radio frequency coupler configured to couple at least a portion of a transmission power of a transmission line coupled to the antenna tuner such that the coupled port carries a first signal indicative of an incident power transmitted to an antenna coupled to the antenna tuner and the terminated port carries a second signal indicative of a reflected power reflected by the antenna. the control path may also include a control module configured to communicate the one or more control signals to the antenna tuner for controlling the impedance of the antenna tuner based at least on the first signal and the second signal. | 09-27-2012 |
| 20130040586 | SYSTEM AND METHOD FOR IMPROVING POWER EFFICIENCY OF A TRANSMITTER - In accordance with some embodiments of the present disclosure, a circuit comprises a balun configured to receive a radio frequency (RF) signal at a first input port and a second input port of an input coil. The balun is further configured to output the RF signal at an output coil communicatively coupled to the input coil. The circuit also comprises a supply voltage selector circuit coupled to the input coil and configured to adjust a bias voltage at the input coil according to a power level of the RF signal received at the input coil. | 02-14-2013 |

| 20130039368 | SYSTEM AND METHOD FOR FREQUENCY-AGILE TRANSMISSION IN A WIRELESS COMMUNICATION DEVICE - In accordance with some embodiments of the present disclosure, a method may include determining a range of frequencies allocated to resource blocks to be transmitted during a subsequent sub-frame slot or sounding reference symbol sub-slot. The method may also include determining an approximate center frequency of the range of frequencies. The method may additionally include modulating resource blocks of the sub-frame or sounding reference symbol sub-slot at the approximate center frequency. The method may further include transmitting the modulated resource blocks at the approximate center frequency. | 02-14-2013 |
| 20130039434 | SYSTEM AND METHOD FOR A DUAL-PATH TRANSMITTER - In accordance with some embodiments of the present disclosure, a transmitting path comprises a digital to analog converter (DAC) configured to receive digital data signals and convert the digital data signals into analog data signals. The transmitting path further comprises a first transmission protocol path and a second transmission protocol path configured to receive a first data signal and second data signal, respectively, from the DAC. The first data signal is associated with a first transmission protocol and the second data signal is associated with the second transmission protocol. The transmitting path additionally comprises a mixer coupled to the first and second transmission protocol paths and configured to receive at least one of the first data signal and the second data signal and modulate at least one of the first data signal and the second data signal onto a carrier signal to generate a radio frequency (RF) signal. | 02-14-2013 |
