Comparative Study Between Gilbert and Cascode Mixers for 5G mm-Wave Systems
摘要
In this paper we compare the behavior and performance of two up-conversion mixers: the cascode cell and the Gilbert cell. Both mixers are designed for communication systems operating at millimeter-wave frequencies. They are designed using MMIC technology based on 0.15 µm GaAs pseudomorphic HEMT. The simulation shows that the cascode cell circuit has a conversion gain CG of 4.8 dB for an IF input power of – 21 dBm. On the other hand, the Gilbert cell achieves a CG of 5.4 dB for an IF power of − 4 dBm.
