Method for amplifying radio signals between a terminal device and an antenna in a first frequency band and in a second frequency band

Method for amplifying radio signals between a terminal device and an antenna in a first frequency band and in a second frequency band

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, th...

description 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.
