Patent number: 11855678Abstract: Amplification of received signals in the first and second frequency bands is activated in the absence of a transmission signal in the circuit arrangement in both the first frequency band and the second frequency band. In response to a detection of a transmission signal in the circuit arrangement, the detected transmission signal is checked as to whether the detected transmission signal can be unambiguously assigned to the first frequency band or the second frequency band. If the check reveals that the detected transmission signal cannot be unambiguously assigned to the first frequency band or the second frequency band, a first transmission amplifier path for amplifying the transmission signal in the first frequency band and a first receiving amplifier path for amplifying received signals in the first frequency band are activated.Type: GrantFiled: October 17, 2018Date of Patent: December 26, 2023Assignee: MOLEX CVS DABENDORF GMBHInventors: Helmut Kautge, Lars Lehmann, Marcus Weigelt

Patent number: 11646755Abstract: Methods and devices are disclosed for amplifying radio signals between a terminal and an antenna or an antenna connection of a circuit having an amplification unit and a detector unit, which has signal branches designed for different frequency ranges, and a power detector. A transmission signal received by the terminal is divided into at least a first signal part and a second signal part. The first signal part is applied to the signal branches of the detector unit. A frequency range of the first signal part is determined by sequential application of the signal branches of the detector unit to the power detector for evaluating a power of the first signal part. For the second signal part, the signal routing in the amplification unit is adjusted based on the frequency range determined by the detector unit. At least the second signal part is amplified by the amplification unit.Type: GrantFiled: November 6, 2018Date of Patent: May 9, 2023Assignee: MOLEX CVS DABENDORF GMBHInventors: Helmut Kautge, Lars Lehmann, Helmut Nast, Ahmed Sayed, Josef Hecht
