arxiv.orgFebruary 2, 2008 E. Rubiola Tutorial on mixers 5 1 Basics It is firstto be understoodthat the mixer is mainly intended, and mainly doc- umented, as the frequency converter of the superheterodynereceiver (Fig. 1). The port names, LO (local oscillator, or pump), RF (radio-frequency), and IF (intermediate frequency) are clearly inspired to this application.
