Mixing arrangement for very high frequencies, in which a high frequency circuit is connected to the mixing stage through a bandpass filter comprising two circuits coupled together which are tuned to the incoming frequency and each of which comprises a conductor inner and a conductive envelope, characterized in that the second circuit includes a second inner conductor which is connected to the inlet electrode of the mixing valve, while its opposite end is passed through the walls of the casings and provides a certain degree of additional coupling of the input circuit of the mixing valve with the first tuned circuit, coupling which, for the oscillations of the oscillator, is in phase opposition with respect to the first coupling.
