Abstract: Device enabling a double polarization of two active circuits connected in hyperfrequency to be produced while avoiding a prohibitive proportion of stationary waves comprising two microstrips connected by a capacitor for blocking the continuous voltage ensuring the high frequency connection between the active circuits and two quarter wave lines connected perpendicularly to these microwaves. The distance between the two connection points and the quarter wave lines is equal to three quarters of a wavelength of the central frequency of the operation band.

Abstract: Hyperfrequency band-cut filter enabling the transmitting of a first lower frequency band and cancelling a second frequency band which is absorbed. It is constituted by a compact assembly comprising two blocks fixed to each other and forming a rectangular wave guide whose upper and lower walls are drilled with slots connected to resonant cavities at the second frequency band, hollowed out in the faces opposite to the faces of the rectangular wave guide and comprising, moreover, two plates which are screwed onto said blocks overlying said cavities.
