ABSTRACT:
A radio frequency converter includes a plurality of signal paths for simultaneously processing two RF signals in the same band but with different polarizations, each of which includes a mixer and an oscillator. A common resonator is connected to the frequency control terminal of each of the oscillators and the oscillators work in a push-push configuration.
