Abstract

A SiGe sub-harmonic down-conversion mixer using a novel active anti-parallel diode pair is presented for millimeter-wave applications. The proposed architecture can help reduce conversion loss and also lower the required local oscillator power. With an LO power of 0 dBm, the measured 2times conversion gain varies from -5 to -7.8 dB in the 50 to 65 GHz range. Compared to earlier reports of millimeter-wave SiGe and GaAs sub-harmonic mixers requiring 5 to 10 dBm of LO power, this circuit achieves similar conversion loss with an LO power as low as -7.5 dBm, while consuming only 0.5 mW of DC power.
