    Abstract: In accordance with various aspects of the disclosure, devices and methods are disclosed that include measuring, at a transmitter, a reflected power level corresponding to a specific transmit power level, and setting the transmit power to an operational level. At the transmitter, a new operational level of the transmit power may be determined, for example, by selecting at least one trial transmit power level, and based on reflected power levels measured corresponding to the operational level and the at least one trial level of the transmit power, either maintaining the operational level as the new operational level, or determining the at least one trial level as the new operational level. The operational transmit power level may correspond to a lowest reflected power level, or a highest rate of change of the reflected power level with respect to the transmit power level.

    Abstract: A technique includes detecting a phase difference between an input signal and a first signal. A second signal is generated that has a fundamental frequency indicative of the phase difference. The second signal is modulated to produce the first signal. Preferably by using single side band modulation. The second signal is produced by a voltage controlled osiellator (62) in a phase locked loop (PPL) and said fundamental frequency is slight by offset from the frequency of said first signal. The first signal is used as the output signal of the PLL (50) and exhibits a reduced noise as compared to the noise present in the output signal if the output signal had the same fundamental frequency as the VCO (62).

    Abstract: An antenna (20) for a wireless device may be kept dynamically tuned to a desired center frequency to compensate for detuning which may be caused by environmental influences. A sensor (38) provides a feedback signal to a controller (34) to select an appropriate capacitance value from a variable capacitor (30, 32) to tune the antenna for the wireless device. The variable capacitor (30, 32) may comprise a plurality of fixed capacitors (50, 52, 54, 56, 58) and MEMS switches ( 60, 62, 64, 66, 68) arranged in parallel or may comprise a variable MEMS capacitor having a fixed lower plate (72) and a flexible upper plate (74).
