Abstract
A slot-line for a microwave device in which is mounted at least one diode connected in parallel between two metallic strips of the slot. At high frequencies (18 to 200 GHz), the inductance L of the diode connections presents a not-negligible impedance which makes it difficult to use the diode. The device in accordance with the invention comprises a slot-line reentrant circuit which provides compensation for the diode inductance and is constituted by a metallic section which is coplanar with the line and connected in series with the diode. The compensating section is short-circuited or open-circuited with respect to the metallic strip in which it is reentrant. The electrical length of the compensating section is adjustable by means of wire, conductive varnish or metal pads.
