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.
在使用微波下变频器GSD2D3D的过程中,发现其本振电路易受环境温度影响,并且本振电路的中心频率随着环境温度的变化发生偏移。
