摘要： A wireless mobile terminal includes an antenna, a power amplifier coupled to the antenna, a power detector coupled to an output of the power amplifier, a phase shifter coupled between the output of the power amplifier and the antenna, and a controller coupled to the phase shifter. The power detector is configured to detect a power of a signal provided by the power amplifier. The controller is configured to adjust the phase shifter responsive to the detected signal power. More particularly, the controller may be configured to adjust the phase shifter to modify a phase component of a reflection coefficient of a load impedance at the power amplifier output without substantially altering a magnitude of the reflection coefficient. Related methods and computer program products are also discussed.

摘要： A voltage controlled oscillator, such as a VCXO (Voltage Controlled Crystal Oscillator), for generating a desired reference frequency in a wireless terminal with a reduced start-up time is described herein. According to the present invention, the VCXO comprises an oscillator that generates the desired reference frequency based on a variable voltage applied to the oscillator by a voltage controller. In addition, the VCXO includes a start-up controller that applies a bias voltage to an oscillator input node to reduce a capacitance associated with the oscillator, and therefore, to reduce the start-up time without negatively impacting the DC current consumption or the tuning range of the VCXO.

摘要： A method and apparatus for improving the efficiency of a multi-band antenna in a wireless terminal over a wide range of frequencies is described herein. To compensate for the undesirable coupling that occurs in a low frequency band between a parasitic antenna and a primary antenna in certain designs, a matching network is connected to at least one ground port of the multi-band antenna. The matching network controls the multi-band antenna performance based on the current transmission frequency band. In some embodiments, the matching network is configured to operate as an open circuit when multi-band antenna operates in the low frequency band, and to operate as a short circuit when multi-band antenna operates in the high frequency band.

摘要： A system and method for suppressing spurious signal leakage in a mobile terminal antenna interface without degrading switch linearity or system insertion loss is disclosed. The antenna interface includes an antenna port, a receive port, a transmit port, and a plurality of switch modes, that may include a receive mode, a transmit mode, and a special isolation mode. To suppress spurious signal leakage from high band transmit and receive ports, a switching mechanism is employed to isolate the receive port from the antenna port in high band transmit mode, and to isolate the transmit port from the antenna port in high band receive mode. A special isolation mode allows simultaneous isolation of the high band transmit and receive ports from the antenna port in low band transmit and receive modes. DC current control circuitry is optionally employed to reduce current drain in transmit and special isolation modes, extending battery life.

摘要： Selectively engaged antenna matching for a mobile terminal. Antenna matching can be engaged, disengaged, or switched as needed depending on whether a movable cover or clam-shell portion of a mobile terminal is open or closed. A switch can connect a single matching network to a radiating element in one case, and disconnect the single matching network from the radiating element in the other case. Alternatively, the switch can connect one matching network to the radiating element to achieve one matched condition, and the other matching network to the radiating element to achieve the other matched condition. In other embodiments, a switchable matching arrangement can alter the signal and/or ground feed points of an antenna. The technique can be applied to planar, fixed external, or collapsible antennas.
