PURPOSE: A mixer circuit for a mixer oscillator phase locked loop is provided to an adjacent channel eliminate performance without complex configuration. CONSTITUTION: In a mixer circuit for a mixer oscillator phase locked loop, a first trap filter(100) performs a trap of a first frequency band. A second trap filter(200) is connected to the first trap filter, and the second trap filter performs trap of the second frequency band. An impedance controller(300) is connected to the first trap filter and the second trap filter. |
