A new FET frequency multiplier

A new FET frequency multiplier is presented. The FET multiplier works in a similar way as a resistive mixer. The FET can be operated either as a series or a parallel switch. The multiplier has essentially no DC power dissipation and its stability properties are good, since the drain-to-source bias-voltage is zero. The multiplier is insensitive to device parameter variations. Different configurations are analysed. The preliminary measurements show a conversion loss of 4.5 dB. The authors believe that the conversion efficiency can be further improved.
