    • 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 multi-band RF transmitter structures that employ separate collectors and modulators. An associated RF amplification method that employs a common collector is also provided.
    • 提供了诸如雷达发射器或通信放大器的RF发射器(20),其包括多个共享共同集电极(38)的RF功率管部分(34,36)。 RF管部分(34,36)可以包括本领域已知的速调管,TWT管或其它RF功率管。 通常还提供通用调制器来调制在多个管段(34,36)中的每一个中产生的电子束(48)。 与使用分开的收集器和调制器的已知多频带RF发射机结构相比,根据本发明的RF发射器(20)相对较轻且更小。 还提供了使用公共收集器的相关RF放大方法。
