摘　　要：在-40～40℃温度变化条件下,实验测试了Herotek TD1018型、M/A-COM 2085型和＂宇林＂牌3种检波器的性能变化情况。结果表明：Herotek TD1018型检波器在0～40℃范围内,相同注入功率下检波电压变化较小,仅为2mV,在0℃以下,相同注入功率下随着温度的降低,检波电压有所上升;M/A-COM 2085型检波器在-40～40℃范围内,检波稳定性相对较好,相同注入功率下检波电压仅有2mV左右的变化;＂宇林＂牌检波器在相同注入功率下检波电压随温度的下降而下降。因此,在应用各种检波器时,需根据环境温度,实验标定检波器的性能。This paper presents the experimental results of Herotek TD1018M/A-COM 2085 and YULIN detectors at temperatures from -40℃ to 40℃.It is shown thatfor the same input powerthe detection voltage of Herotek TD1018 changes littlewhich is only 2 mV at the temperature from 0℃ to 40℃but it rises with the decline of the temperature when the temperature falls below 0℃The detection voltage of YULIN drops with the fall of the temperature.M/A-COM 2085 has a better stability than the other two detectors dur-ing the experimentwith only 2 mV changes in the voltage.The test results reveal that the detectors should be calibrated before the experiment according to the actual temperature.
