microwave frequency down-converter

In the process of using the microwave frequency down-converter,the local oscillation circuit is easily affected by undulate temperature,so center frequency of local oscillation circuit will depart with the undulate temperature.
在使用微波下變頻器GSD2D3D的過程中,發現其本振電路易受環境溫度影響,竝且本振電路的中心頻率隨著環境溫度的變化發生偏移。
