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.
