20110263270 | METHOD AND SYSTEM FOR SHARING A SIGNAL RECEIVED BY AN ANTENNA - Described are a method, system, and mobile communication device for sharing a signal received by an antenna. A signal, such as a signal sent from a global positioning system, is received by the antenna. An amplifier is then used to generate an amplified signal. The amplifier is located an attenuation distance away from a noise source. The amplified signal is divided into a first divided signal and a second divided signal, which are respectively transmitted to first and second signal utilization modules. While being transmitted from the antenna to the first and second signal utilization modules, the signal suffers propagation losses. While locating the amplifier remote from the noise source decreases noise strength, which positively contributes to signal-to-noise ratio, it also increases propagation losses, which negatively contributes to signal-to-noise ratio. The method, system and mobile communication device are designed such that this positive contribution exceeds this negative contribution, resulting in an overall benefit to signal-to-noise ratio. Also beneficially, sharing the signal allows one antenna to be used for both signal utilization modules, lowering manufacturing costs and saving space in the mobile communication device. | 10-27-2011 |

20090021374 | METHOD AND SYSTEM FOR RADIATED POWER CONTROL FOR SHORT RANGE RFID TAG READING - A method and system for power control for Radio Frequency Identification (RFID) tag reading is provided. The system includes a power amplifier for providing an RF transmit signal for the RFID tag reading. The RF transmit signal is provided to an antenna for radiating the transmit signal. The power of the radiated transmit signal defining a read range for the RFID tag reading. The system includes an attenuator provided between the power amplifier and the antenna for controlling the power of the radiated transmit signal to adjust the read range. A handheld RFID reader may include the system. The method includes calibrating the output power of a reader having a power amplifier and an attenuator provided between the power amplifier and an antenna. The step of calibrating includes at least one of controlling power of the power amplifier in its linear region, and controlling attenuation level of the attenuator. | 01-22-2009 |
