Abstract: A single tone RF signal generator and a method of generating a single tone RF signal. The single tone RF signal generator includes an output and a power amplifier that has an input. The power amplifier is operable to receive an RF signal including a first harmonic corresponding to a single tone signal to be produced by the signal generator. The power amplifier is also operable to amplify the RF signal. The power amplifier is further operable to provide the amplified RF signal to the output of the signal generator. The single tone RF signal generator further includes a feedback circuit connected between the output of the signal generator and the input of the power amplifier. The feedback circuit is configured to add one or more predistortion harmonics to the RF signal received by the power amplifier for cancelling harmonics in the amplified RF signal provided by the power amplifier.

Abstract: Wireless receivers and related methods with interferer immunity are disclosed. The receiver includes a receive (RX) front-end, a power level detector, and an automatic gain controller (AGC). The RX front-end includes circuit(s) having variable gains, and the power level detector outputs a power level indicator. The AGC receives the power level indicator and outputs the gain settings to the variable-gain circuits within the RX front-end. Further, the AGC is configured to adjust the gain settings within a first gain range when not receiving data frames and to adjust them within a second gain range when receiving data frames. The second gain range is a restricted version of the first gain range. Further, the AGC can be configured to detect and store gain settings within a sliding time window when data frames are not being received and to use these stored gain settings to determine the second gain range.

Abstract: An amplifier includes a supply voltage terminal and a reference voltage terminal and an input terminal. An amplifier arrangement includes a first and second branch coupled between the supply and reference voltage terminals, and one or more transistors configured to provide current flow through each of the branches based on the input signal at the input terminal. A first output terminal is coupled to the first branch to provide a first output signal based on the current flow therethrough. A second output terminal is coupled to the second branch to provide a second output signal based on the current flow therethrough. An impedance-modifying circuit is coupled to the second output terminal to provide a voltage variation in the second output signal in response to the input signal greater than a voltage variation in the first output signal in response to the input signal.
