Title (EN) MICROWAVE DIODE TUNING CIRCUIT
(FR) CIRCUIT DE SYNTONISATION DE DIODE A MICRO-ONDE
Abstract: front page image
(EN)A microwave diode tuning circuit including an IMPATT diode holder of coaxial form and an adjustable capacitor connected in a parallel resonant circuit by microstrip transmission line. The tuning circuit includes a stabilization network and a bias insertion network. Optionally, the tuning circuit may include a hybrid junction for coupling two such diode tuning circuits together. The diode holder includes an internally-externally threaded sleeve providing means for continuously adjusting, through a limited range, the inductance of the resonant circuit.
(FR)Un circuit de syntonisation de diode à micro-onde comprend un porte-diode IMPATT de forme coaxiale ainsi qu'un condensateur réglable connecté dans un circuit résonant parallèle par une ligne de transmission microbande. Le circuit de syntonisation comprend un réseau de stabilisation et un réseau d'insertion de polarisation. Eventuellement, le circuit de syntonisation peut comprendre une jonction hybride pour coupler deux de ces circuits de syntonisation de diode ensemble. Le porte-diode comprend un manchon fileté intérieurement-extérieurement qui constitue un moyen pour régler en continu, sur une plage limitée, l'inductance du circuit résonant.
