ABSTRACT:
An up converter having on the one hand an ultrahigh-frequency ring receiving one of the waves to be mixed and on the other hand a transformer receiving the other wave to be mixed whose frequency is in the radio-electric range. The transformer is connected to the ring through a bridge of mixer diodes which are placed with this transformer and a capacitor for tuning this latter inside the ring. The resulting wave exits from the ring through a waveguide having two traps tuned to the frequency of the wave applied to the ring.
