Title (EN) MULTIPLE BANS OSCILLATOR USING SWITCHED INDUCTORS
(FR) OSCILLATEUR A BANDES MULTIPLES, DANS LEQUEL DES INDUCTANCES COMMUTEES SONT UTILISES
Abstract: front page image
(EN)A voltage controlled oscillator (10) can operate in multiple frequency bands. One or more PIN diodes (20) are connected parallel to inductances (38) and selectively shorts them out. This selectively scales the RF impedance of the tank circuit (16), thereby applying the correct voltages for oscillator (24) to produce the correct frequencies.
(FR)Un oscillateur commandé en tension (10) peut fonctionner dans des bandes de fréquence multiples. Une ou plusieurs diodes PIN (20) sont connectées parallèlement aux inductances (38) et les court-circuitent de manière sélective. Cette sélectivité permet l'échelonnement de l'impédance RF du circuit oscillant final (16), et d'appliquer les tensions correcte pour que l'oscillateur (24) produise les fréquences correctes.
