摘要： A reconfigurable LNA for increased jammer rejection is disclosed. An exemplary embodiment includes an LNA having a tunable resonant frequency, and a detector configured to output a control signal to tune the resonant frequency of the LNA to increase jammer suppression. An exemplary method includes detecting if a jammer is present, tuning a resonant frequency of an LNA away from the jammer to increase jammer rejection if the jammer is present, and tuning the resonant frequency of the LNA to a selected operating frequency if the jammer is not present.

摘要： Techniques for generating oscillator signals in a wireless communication device are described. A phase-locked loop (PLL) may be used to generate an oscillator signal for a selected frequency channel. Different PLL settings may be used for the blocks in the PLL for different frequency channels. The different PLL settings may be for different PLL loop bandwidths, different amounts of charge pump current, different frequency equations associated with different sets of high and low divider ratios, different frequency division schemes associated with different prescaler ratios and/or different integer divider ratios, high side or low side injection for a super-heterodyne receiver or transmitter, and/or different supply voltages for one or more circuit blocks such as an oscillator. A suitable set of PLL settings may be selected for each frequency channel such that adverse impact due to spurs can be mitigated.
