Abstract
A frequency mixer having parallel mixer cores is described that is configured to heterodyne a signal. In an implementation, the frequency mixer includes a first mixer core and a second mixer core. A first balun is connected to the first mixer core and configured to furnish a LO signal occurring in a first range of frequencies to the first mixer core. The mixer includes a second balun coupled to the second mixer core, and the second balun is configured to furnish a LO signal occurring in a second range of frequencies during a second time interval. The mixer includes a first biasing voltage source that is center tapped to the first balun and a second biasing voltage source is center tapped to the second balun to further prevent operation of the at least substantially non-operational mixer core.
