Abstract
A frequency mixer is disclosed. In an implementation, the multi-LO band switched-core includes a single field-effect transistor (FET) ring having a first mixer core and a second mixer core. The first mixer core and the second mixer core configured to connect to a radio frequency (RF) port and an intermediate frequency (IF) port. The frequency mixer also includes a first local oscillator (LO) transformer and a second LO transformer. The first LO transformer is configured to furnish a first LO signal occurring in a first limited range of frequencies to the first mixer core, and the second LO transformer is configured to furnish a second LO signal occurring in a second limited range of frequencies to the second mixer core.
