the last one thx you so so so much
by two orders of magnitude.Unfortunately,the poor resistivity of the silicon substrate does not allow the use of very high frequencies.Use of a high resistivity GaAs substrate with a much lower rf loss will make higher microwave fre- quencies feasible with a corresponding increase in sensitiv- ity.We note that oscillators and mixers can be realized up to several GHz on silicon substrates and several tens of GHz on GaAs substrates.It should be possible to fabricate a large array of sensitive detectors monolithically integrated with their associated electronics.

由二个数量级.不幸地,硅体的粗劣的抵抗力不允许对甚高频的用途.对一个高的抵抗力GaAs 基体的用途以更低的rf 损失将使更高的微波fre- quencies 可行以在sensitiv- 的对应的增量ity .我们注意到,摆动器和搅拌器可能体会由几千兆赫在硅体和几十倍千兆赫决定在GaAs 基体.它应该是可能制造大一些敏感探测器整体地集成以他们伴生的电子.
是这个啦,希望对你有用.
