欧洲空间局(ESA) 已开始执行一项有关先进亚毫米波外差检波特别是本机振荡器所需要的器件研制计划。为了用尽可能少的器件覆盖所关心的频谱范围,就要求有很高的调谐能力。宽带返波振荡器由于它具有连续的电子调谐能力,所以选择这种振荡器看来是最合适的。为了自由选择检波混频器并在0.75—0.95毫米波长范围内具有20％的调谐能力,在覆盖0.5—1毫米波长范围的一系列管子中,把第一个管子的最小输出功率的设计指标定为10毫瓦。
The European Space Agency (ESA) has begun implementing a device development program for advanced submillimeter-wave heterodyne detection, especially for local oscillators. In order to cover the spectrum of interest with as few devices as possible, a high degree of tuning is required. Broadband Back-wave Oscillator Because of its continuous electronic tuning capability, the choice of this oscillator appears to be the most suitable. In order to freely select the detector mixer and have 20% tuning capability in the 0.75-0.95 mm wavelength range, design the minimum output power of the first tube in a series of tubes covering the 0.5-1 mm wavelength range It is 10 milliwatts.
