Abstract

According to the well-known Friis equation the available power gain should be maximized to reduce the overall noise figure. Therefore, in receivers where an LNA is not present or its gain is low, the available power gain of the passive mixer is of interest. However, only the voltage gain is presented in many papers. In this paper an analytical model is presented for the power gain, voltage gain and input and output impedance of a passive mixer. The model is obtained using time-domain analysis since the mixer is periodically time variant. The validity of the models is checked using CMOS 90 nm transistor simulations.
