It is used in 1TX-1RX. Amplitude fluctuation of Raw Data (IF signal) is confirmed near the low temperature state (-4deg), and it is detected as noise in the waveform after FFT. What is the cause of this phenomenon? Is there a control that changes the amplitude of the IF signal in the transmission / reception state? Is there a way to solve this with software?One of the reasons for this is that the TX-RX isolation of our hardware is not sufficient, but we are looking for a way to deal with it with software.
