  • Patent number: 9723560
    Abstract: An apparatus includes a first amplifier stage configured to amplify a first carrier signal. The apparatus includes a second amplifier stage configured to amplify a second carrier signal. A resistive-capacitive (RC) network is coupled to the first amplifier stage and to the second amplifier stage. The RC network includes a resistive element coupled to a capacitive element.

  • Publication number: 20170104507
    Abstract: A receiver, including: a local oscillator (LO) configured to generate a signal with a frequency; a mixer coupled to the LO, the mixer configured to change a first frequency of an input signal to a second frequency based on the generated signal; a baseband filter coupled to the mixer and having a bandwidth; and a controller coupled to the local oscillator, the controller configured to adjust the frequency of the signal to shift the second frequency of the input signal to a third frequency in response to a presence of one or more intra-band jammers that fall within the bandwidth of the baseband filter so that a respective image of the one or more intra-band jammers avoids failing into a respective one of a plurality wanted signals in the input signal.

  • Patent number: 9307549
    Abstract: To support very high QAM rates, a user equipment (UE) needs extremely good signal-to-noise ratio (SNR). Using a receiver configuration that improves SNR comes at the expense of higher power consumption. However, consuming higher power to support very high QAM rates when poor channel conditions are present is a waste of power. By correlating the modulation and coding scheme used by the UE with the UE channel quality estimate, the UE can modify the receiver configuration to improve SNR only when channel conditions support very high QAM rates.

  • Publication number: 20150092681
    Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus determines to change a mode of operation from a first signal-to-noise ratio (SNR) mode to an increased SNR mode, sends channel quality information (CQI) to a base station indicating an ability to receive data at the increased SNR, and receives the data from the base station according to a higher order modulation and coding scheme (MCS) corresponding to the increased SNR when the base station is capable of providing the data at the higher order MCS.
