Abstract
A triple-balanced mixer is disclosed. The mixer features a complementary metal oxide semiconductor (CMOS) mmW (millimeter wave) integrated circuit and adds an inverted double balanced mixer to a double-balanced Gilbert cell mixer to provide a triple-balanced mixer. Another term for this type of mixer is doubly double balanced. Pairs of field effect transistor (FET) devices are interleaved into a single device. The inverted mixer provides an inverted LO feedthrough signal equal in amplitude to the LO feedthrough from the first mixer. The inverted LO feedthrough is used to cancel the LO feedthrough, or leakage, of the first mixer at the RF port.
