以返波振荡器为基体的扫频发生器能提供由微处理器控制的、准确度很高的输出信号,频宽26～180GHz。在现代集成电路和固态构件的世界里,返波振荡器(BWOs)几乎被人们遗忘。然而返波振荡管却是一个极好的毫米波辐射源,而且也可做为高性能毫米波扫频发生器的信号源。俄罗斯ELVA-1公司出产的扫频仪就是这种产品。 BWO为基体的毫米波扫频发生器系列之一,如G4-001AM,它的工作频率从78～118GHz,全频段输出功率大于10mW。它的连续波输出功率电平:在96GHz约为36mW;在115GHz时大于
A swept-frequency generator based on a back-wave oscillator provides a highly accurate output signal controlled by a microprocessor with a bandwidth of 26 to 180 GHz. In the world of modern integrated circuits and solid-state components, BWOs are almost forgotten. However, the return-wave oscillating tube is an excellent source of millimeter-wave radiation and can be used as a source for high-performance millimeter-wave swept generators. Russia ELVA-1 company produced the scanner is such a product. BWO is one of the series of millimeter wave frequency sweep generator basal body, such as G4-001AM, its working frequency is from 78- 118GHz, the full band output power is greater than 10mW. Its CW output power level is about 36mW at 96GHz and greater than at 115GHz
