Title (EN) SELF-BIAS EMITTER CIRCUIT
(FR) CIRCUIT ÉMETTEUR À POLARISATION AUTOMATIQUE
Abstract:
(EN) Self-bias emitter circuit configurations (100, 200, 400, 500, 600) can use the amplitude of an input AC carrier signal to provide a DC bias voltage across an emitter (104) for suitable operation. A self-bias emitter circuit can include a transductor {106} with primary (108) matched with an amplifier, while secondary (110} can be matched to the emitter.
(FR) L'invention concerne des configurations de circuit émetteur à polarisation automatique (100, 200, 400, 500, 600) pouvant utiliser l'amplitude d'un signal de porteuse en courant alternatif d'entrée pour obtenir une tension de polarisation en courant continu à travers un émetteur (104) pour permettre un fonctionnement correct. Un circuit émetteur à polarisation automatique peut comprendre un transducteur {106} pourvu d'un enroulement primaire (108) apparié avec un amplificateur, alors qu'un enroulement secondaire (110) peut être apparié à l'émetteur.
