Summary:The invention discloses a passive double balanced mixer based on double-sided asymptote micro-strip baluns. The passive double balanced mixer comprises a radio frequency micro-strip balun, a local oscillator micro-strip balun and a bridge mixing unit composed of four mixing diodes. The radio frequency micro-strip balun and the local oscillator micro-strip balun are the double-sided asymptote micro-strip baluns. An input end of the radio frequency micro-strip balun is set as the input end of the passive double balanced mixer and is connected with a radio frequency signal. The input end of the local oscillator micro-strip balun is connected with a local oscillator signal. An output end of the radio frequency micro-strip balun and the output end of the local oscillator micro-strip balun are connected with the input end of the bridge mixing unit. The output end of the passive double balanced mixer is an intermediate frequency output port formed by converting the local oscillator micro-strip balun of a double-side
