Abstract
A double balanced active mixer is used for compensating an asymmetric characteristic of complementary radio frequency signals, to thereby improve linearity of the double balanced active mixer. The double balanced active mixer includes an input transistor part for amplifying first and second radio frequency signals having complementary phase each other which are inputted from external circuit and for transferring the amplified first and second radio frequency signals and an Output transistor part for outputting first and second intermediate frequency signals which are complementary each other by switching the amplified first and second radio frequency signals.
