ABSTRACT:
A sub-harmonic mixer is provided, which includes: a mixer core having first and second transistors performing switching operations in response to a local oscillator (LO) signal and a radio frequency (RF) signal; a power source applying bias maximizing nonlinearity of a transistor included in the mixer core; an RF port applying an RF signal to the mixer core; an LO port applying an LO signal to the mixer core; and first and second phase delay circuits in which the RF signals applied to the first and second transistors have a 180-degree phase difference.
