✦ Synopsis

PM-HFET cold mixer is the good linearity of the i.f. output power with a rf power compression point of 11 dBm. More-Ž . over, moderate conversion losses 7 dB are obtained with no dc consumption. For the dual-gate mixer the main advantage Ž . is the high natural LO to rf isolation 30 dB . An interesting conversion gain is also shown, and the device avoids external LO to rf coupling.

In this study, an exhaustive and accurate methodology is carried out. It is based on specific characterizations, in-house nonlinear modeling, circuit design using commercial harmonic balance software, complete measurement of the structures, and reverse engineering. The two topologies investigated are very attractive for the fabrication of mixers in millimeter waves. Because of the different advantages exhibited, the choice between the two devices will depend on the specifications and constraints of the envisaged application.
