A centimeter-wave-band frequency multiplier in a sealed-off envelope with two helices through which a common electron beam pass was constructed and investigated. For a multiplication ratio of three, a positive conversion coefficient of the order of 30 dB is obtained. It is established that the maximum output power of the multiplier is comparable with the power delivered by the second stage under saturation conditions when used as an amplifier. The possibility of operating the multiplier over a wide frequency band is demonstrated.
