    Abstract: 本開示は、一般に、無線通信システムにおける受信機構造の分野に関し、より詳細には、受信機構造におけるパッシブミキサと、第1の周波数を有する第1の信号を、第2の周波数を有する第2の信号に、第3の周波数を有する第3の信号を使用することによって、変換する、技術とに関する。 第3の周波数を有する第3の信号を使用することによって、第1の周波数を有する第1の信号を、第2の周波数を有する第2の信号に変換する、パッシブミキサが、キャンセル値で加重された第1の信号を、第3の信号に重畳することによって、2次混変調成分を打ち消す第1のキャンセル信号を生成する、キャンセルコンポーネント220と、第1の信号を受信する第1の端子232と、第2の信号を出力する第2の端子234と、第1のキャンセル信号を受信する第3の端子236とを有する混合コンポーネント231とを備え、混合コンポーネント231が、第1の端子232で入力として与えられる第1の信号と、第3の端子236で入力として与えられる第1のキャンセル信号とを混合することによって、第2の端子234での出力として、第2の信号を与えるように適合される。

    Abstract: The present disclosure generally relates to the field of receiver structures in radio communication systems and more specifically to passive mixers in the receiver structure and to a technique for converting a first signal having a first frequency into a second signal having a second frequency by using a third signal having a third frequency. A passive mixer for converting a first signal having a first frequency into a second signal having a second frequency by using a third signal having a third frequency comprises a cancellation component 220 for generating a first cancellation signal for cancelling second order intermodulation components by superimposing the first signal weighted by a cancellation value on the third signal; and a mixing component 231 having a first terminal 232 for receiving the first signal, a second terminal 234 for outputting the second signal, and a third terminal 236 for receiving the first cancellation signal, wherein the mixing component 231 is adapted to provide the second signal as output at the second terminal 234 by mixing the first signal provided as input at the first terminal 232 and the first cancellation signal provided as input at the third terminal 236.
