Patent ID: 7107035

Claim:
A frequency converter comprising: a first transconductance unit that outputs a first output signal based on a first input signal having a first frequency; a first inductor through which the first output signal passes; a first current switching unit that converts the first output signal passing through the first inductor to a second output signal having a second frequency based on a local oscillator signal, the first inductor being connected between the first transconductance unit and the first current switching unit; a second transconductance unit that outputs a third output signal based on a second input signal having a phase that is opposite to a phase of the first input signal; a second inductor through which the third output signal passes; and a second current switching unit that converts the third output signal passing through the second inductor to the second output signal based on the local oscillator signal, the second inductor being connected between the second transconductance unit and the second current switching unit.
