Hi, I am currently using the baseband transmission in the HMC6350 system.
When no signal is input at the HMC6300 transmitter end, the receiver end still receives a signal around 40 kHz (as shown in the figure). Is this signal caused by beat frequency resulting from a clock frequency deviation between the transmitter and receiver ends? Is there a solution for this?
