MIXER |
摘要 |
A mixer includes a first node to which an intermediate frequency (IF) signal is input; first and second transistors that respectively have control terminals supplied with local signals having mutually opposite phases and output terminals connected to the first node; a first filter that is connected between the output terminal of the second transistor and the first node and suppresses passage of the IF signal; a second node to which the IF signal is input; third and fourth transistors that respectively have control terminals supplied with local signals having mutually opposite phases and output terminals connected to the second node; a second filter that is connected between the output terminal of the fourth transistor and the second node and suppresses passage of the IF signal; and a combiner combining a signal output from the first node and a signal output from the second node. |

1. A mixer comprising:
a first node to which an intermediate frequency (IF) signal is input; first and second transistors that respectively have control terminals supplied with local signals having mutually opposite phases and output terminals connected to the first node; a first filter that is connected between the output terminal of the second transistor and the first node and suppresses passage of the IF signal; a second node to which the IF signal is input; third and fourth transistors that respectively have control terminals supplied with local signals having mutually opposite phases and output terminals connected to the second node; a second filter that is connected between the output terminal of the fourth transistor and the second node and suppresses passage of the IF signal; and a combiner combining a signal output from the first node and a signal output from the second node.
