Abstract:
    An amplifier arrangement for ultra-wideband, UWB, applications and. a method to amplify a UWB signal are presented. A transistor, whose control input forms an input of the arrangement, is connected to a resonant circuit having a controllable resonator frequency. At the resonator circuit, an output of the arrangement is formed. The resonant circuit includes a frequency determining inductance whose value is controllable. By doing this, it is possible to preselect different frequency bands, while achieving the same gain characteristics in each band.
