摘要： Technique for reducing local oscillator leakage in integrated frequency conversion circuits. The technique includes the step of coupling an external portion (35) of a resonator circuit (31, 35) to the integrated frequency conversion circuit (200). The coupling is accomplished without using any of the DC power or ground pins of the conversion circuit. A frequency conversion circuit based on this technique includes resonator, oscillator, and mixer circuits. Part of the oscillator and mixer circuit (16, 13) is encapsulated in a package (200), whereas at least a portion of the resonator circuit (35) is located outside the package. The outside portion of the resonator circuit (35) connects to at least two external resonator pins (43a, 43b) of the package (200) such that, during the operating of the conversion circuit, the net current entering the package via said external resonator pins (43a, 43b) is approximately zero.
