摘　　要：针对传统宽带变频接收机的变频增益波动调试方法不够灵活且耗时长的缺点,提出了一种改进的增益波动调试及设计方法。需要先在接收机和模块设计时预留出控制接口,然后通过数字化手段完成变频增益的自动测试和不同频点的衰减控制,从而实现对宽带变频接收机增益波动的快速调整。实测结果证明,采用这种设计方法能够灵活快速地完成增益波动调试,达到设计目标。In view of the disadvantage of the gain fluctuation debugging method of the conventional wideband down conversion receiver,which is not flexible and time-consuming,a debugging and designing method to improve the gain fluctuation is proposed in this paper.The control interface should be reserved in the design of the receiver and module first.Through the digital means to complete the automatic test of the conversion gain and attenuation control of different frequencies,it will make it possible to fast adjust the gain fluctuation of the wideband down conversion receiver.The actual measured results show that the design method can be used to debug the gain fluctuation flexibly and quickly,and the design objective is achieved.
