ABSTRACT:
A frequency converting or mixing device for a receiver, particularly employing hollow conductor or micro strip techniques, including signal and oscillator input means, a diode as a non-linear element, an intermediate frequency output and two stub circuits at the signal input side of the diode, at a mutual distance of approximately one-fourth signal input wave length, for effecting a blocking of currents, of the second harmonic of the oscillator frequency and the summation frequency of the signal input frequency and oscillator frequency, at the diode.
