ABSTRACT:
A traveling-wave amplifier tube adapted for use as a booster of transmitted signals has very small internal circuit attenuation so that it may be used without an electron beam as a transparent, passive path for low transmitter power. When the booster tube's beam is excited, the signal is amplified about 10dB. Upper bandedge instabilities in the lossless tube are inhibited by a lower cutoff frequency of the circuit near the output end than near the input end, so that bandedge power can flow both ways out of the large-signal output end.
