  • Increasing sensitivity of radio receiver
    Patent number: 8433273
    Abstract: A direct-conversion radio receiver is provided. The receiver includes a first measurement unit configured to measure a signal level of a received signal at an input of the receiver. The receiver also includes a gain controller configured to stepwise adjust at least a front-end gain and a baseband gain of the receiver when the signal level of the received signal at the input of the receiver exceeds a given sensitivity level, and adjust the front-end gain with at least one further gain step when the input signal level is below the given sensitivity level.
    Type: Grant

  • Antenna matching measurement and amplification control
    Publication number: 20070270174
    Abstract: A transceiver with amplification control comprises the following. A coupler samples a part of a radio frequency signal proceeding between an amplifier unit and an antenna of the transceiver. A converter down converts the sampled radio frequency signal. A measuring unit measures strength of the down converted radio frequency signal. A controller controls at least one parameter of the amplifier unit as a function of the measured strength.
