An RF transmitter (20), such as a radar transmitter or a communications amplifier, is provided that includes a plurality of RF power tube sections (34, 36) each sharing a common collector (38). The RF tube sections (34, 36) may comprise Klystron tubes, TWT tubes or other RF power tubes known in the art. A common modulator is also typically provided to modulate electron beams (48) produced in each of the plurality of tube sections (34, 36). The RF transmitter (20) according to the present invention is considerably lighter and smaller relative to known mufti-band RF transmitter structures that employ separate collectors and modulators An associated RF amplification method that employs a common collector is also provided.
Emetteur RF (20), tel qu'un émetteur radar ou un amplificateur de communication, comprenant une pluralité de sections de tube de puissance RF (34, 36) partageant chacune un collecteur commun (38). Ces sections de tube RF (34, 36) peuvent consister en des tubes Klystron, des tubes à onde progressive (TOP) ou d'autres tubes de puissance RF de l'état actuel de la technique. Un modulateur commun sert à moduler les faisceaux d'électrons (48) produits dans chacun de la pluralité de sections de tube (34, 36). Cet émetteur RF (20) est considérablement plus léger et plus petit par rapport à des structures connues d'émetteur RF à bande multiple mettant en application des collecteurs et des modulateurs séparés. L'invention concerne également un procédé associé d'amplification RF mettant en application un collecteur commun (38).
