Title (EN) HIGH-LINEARITY QUADRATURE HYBRID ATTENUATOR
(FR) ATTÉNUATEUR HYBRIDE EN QUADRATURE À HAUTE LINÉARITÉ
Abstract:
(EN) Various arrangements of a PIN diode attenuator circuit are presented. The PIN diode attenuator circuit may include a quadrature hybrid coupler. The PIN diode attenuator circuit may include a direct current (DC) feed circuit comprising an adjustable DC voltage source. PIN diode attenuator circuit may include first and second PIN diode circuits connected with ports of the quadrature hybrid coupler. Each PIN diode circuit may include a PIN diode having a first cathode of the first PIN diode directly connected to a ground potential and a first anode of the first PIN diode connected with the DC feed circuit and the quadrature hybrid coupler.
(FR) La présente invention concerne divers agencements d'un circuit d'atténuateur à diode PIN. Le circuit d'atténuateur à diode PIN peut comprendre : un coupleur hybride en quadrature ; un circuit d'alimentation en courant continu (CC) comportant une source de tension continue ajustable ; et des premier et second circuits à diode PIN raccordés à des ports du coupleur hybride en quadrature. Chaque circuit à diode PIN peut comprendre une diode PIN, une première cathode de la première diode PIN étant directement raccordée à un potentiel de masse et une première anode de la première diode PIN étant raccordée au circuit d'alimentation en CC et au coupleur hybride en quadrature.
