Abstract
The V-I characteristic of Josephson junction with an external parallel admittance, the high frequency impedance and high frequency response of a Josephson junction to small external signal are calculated by analytical method. The experimentally obtained spectral response curves for the superconducting point contacts in the frequency range 5-30 cm-1 are presented. The condition need for achieving high sensitivity of superconducting point contacts and superconducting bridges are determined.

Résumé
On présente les calculs, de la caractéristique V-I d'une jonction Josephson shuntée par une résistance, de son impédance en haute fréquence et de sa réponse à un petit signal externe. On donne les courbes expérimentales obtenues dans le domaine de longueurs d'onde de 5 à 30 cm et on précise les conditions optimales de fonctionnement pour les contacts à pointes et les microponts.
