The antenna amplifier has an antenna connection (1), and a transmitter connection (2) coupled to same via a first bandpass filter (Tx) for transmitter frequencies. A receiver frequency amplifier input is connected to the antenna connection via a second bandpass filter (Rx1). The amplifier has an output that is connectable to the receiver. The filters are mounted in a common elongated cavity and include comb-line type resonators arranged in rows along a cavity mean line. The antenna amplifier has connector pins at the two mutually approaching ends of the two filters and at the two outer ends. |
