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 beam s (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 empl oy separate collectors and modulators. An associated RF amplification method th at employs a common collector is also provided.
