Abstract
A balanced up-conversion mixer includes: a negative resistance compensation circuit generating and outputting first and second currents based on a DC bias voltage; a mixing circuit allowing a differential radio frequency current (DRFC) signal pair to flow thereinto based on the first and second currents from the negative resistance compensation circuit, a differential oscillating voltage (DOV) signal pair and a differential intermediate frequency voltage (DIFV) signal pair; and a load circuit outputting a differential radio frequency voltage signal pair based on its impedance, the DC bias voltage and the DRFC signal pair. The DRFC signal pair has a frequency associated with those of the DOV and DIFV signal pairs.
