Abstract

Low imbalanced and fully matched active baluns have been designed for 21GHz up-conversion Gilbert mixer’s ports. It consists of a common-gate FET and a common-source FET with input and output matching networks. The balun has been realized in 0.25μm GaAs pHEMT process. Simulation shows that the phase error of LO balun could be controlled within 2 degrees over the frequency of 3-6GHz, and the phase error of IF balun could be controlled within 3 degrees over the frequency of 16-18GHz.All ports are matched at the impendence of 50Ω for mixer use. The inhibition of the Gilbert mixer using proposed active baluns is more than 40dBc.
