I am testing the mm-wave a transmitter (EV2HMC7585LG) and a receiver (EV2HMC8327LG). They are directly connected with a 30dB attenuator.
However, I can see nothing from the IF outputs, even applying FFT for the received signals. Are my connections correct?
Also, there are many jumper connections on the boards. One is disconnected by default. I do not know exactly what are those jumpers used for. Is there any user guide I can refer?
I belive you can use low frequences. I think IF input of upconverter is DC coupled. I'm not sure about downconverter. But anyway khz should be Ok. I have posted a new topic here requesting the schematics…
Could you report your current consumption on P5V and N5V before and after jumper 1-2 is attached?
It is working finally based on the instruction. I was not connecting VCTRL to 5V.
Right now, I have another question. The radio frequency is 6*LO + IF, or 6*LO - IF?
