  • AUTOMATIC GAIN CONTROL CIRCUIT AND LOW NOISE AMPLIFYING CIRCUIT
    Publication number: 20090096527
    Abstract: By connecting an antenna damping circuit (4) and a bypass switch (5) in series and connecting the series circuit and an LNA (3) in parallel, it is possible to inhibit a generation of a signal path for connecting the bypass switch (5) to the LNA (3) in series in an operation of the LNA (3) and to prevent a noise factor of the LNA (3) from being deteriorated due to an on resistance of the bypass switch (5).
