backward-wave oscillator

[′bak·wərd ‚wāv ′äs·ə‚lād·ər]

(electronics)

An electronic device which amplifies microwave signals simultaneously over a wide band of frequencies and in which the traveling wave produced is reflected backward so as to sustain the wave oscillations. Abbreviated BWO. Also known as carcinotron.
