  • Circuit layout and method for frequency-dependent matching of a high-frequency amplifier stage
    Patent number: 9270240
    Abstract: A circuit for frequency-dependent matching of a high-frequency amplifier stage includes high-frequency stage with an output to a total high-frequency path that divides a total frequency band into a plurality of partial frequency paths for respectively preset partial frequency bands. The outputs of the plurality of partial frequency paths are reunited again into the total high-frequency path, following the processing of the partial frequency bands of these partial frequency paths. The partial frequency paths include a matching network surrounded by a first and second pass filter. At least one partial frequency path is switchable, when a control signal is supplied thereto.
