- Omsättare från en frekvens till en annan med frekvensmultiplikatorer
- Ligger oscillatorfrekvensen under nyttosignalen kan nyttosignalens högre frekvens blandas direkt till konverterns/transverterns högre utfrekvens
- Ligger oscillatorfrekvensen över nyttosignalen inverteras en SSB-signal (USB
\rightarrowLSB och LSB\rightarrowUSB)
