  • Bandpass filter providing wide gain control range
    Patent number: 9698738
    Abstract: A bandpass filter that provides a wide gain control range is provided. The bandpass filter performs channel filtering and gain control while maintaining the bandpass characteristic of the bandpass filter. The bandpass filter enables gain control for a wide signal amplitude range while maintaining performance characteristics, such as an out-of-band attenuation ratio capable of high linearity and good pass-band flatness.
