本文将介绍一个Ku-Band振荡器,它可以从16.0GHz调谐到16.5GHz,具有直流变换到射频的效率为19％,并具有好的噪声性能。该振荡器比工作在同样频率下的典型的过渡电子振荡器(TFO)的效率大约高10倍多。因此特别适用于在直流功率方面严格受限制的系统,例如人工携带的雷达,电池工作的微波无线电以及卫星发射机应荅器。 该振荡器设计的关键因素是大信号条件下FET的性能,(是在圆1中所示的大功率反射计的帮助下实现的)俈外加到一个商用的共源FET~1工偏压极性的反相,使固定在试验架上的FET工作在共漏状态。连接在源端的滑动的短路线为调整源和漏之间的
This article introduces a Ku-Band oscillator that can be tuned from 16.0 GHz to 16.5 GHz, has a DC to RF conversion efficiency of 19%, and has good noise performance. The oscillator is about 10 times more efficient than a typical TFO operating at the same frequency. It is therefore particularly suitable for systems that are strictly limited in terms of DC power, such as manually carried radars, battery operated microwave radios, and satellite transmitters. A key factor in this oscillator design is the performance of the FET under large signal conditions, which is achieved with the help of a high-power reflectometer as shown in circle 1, plus a common-source FET to a commercial bias voltage Sexual inversion, so fixed in the test frame FET work in a total drain state. The short line of the slip connected to the source is to adjust the source and drain
