Hi,
I am designing an FMCW-GPR. My question is about the mixer. We are hoping to keep the IF very low (~10kHz) to make ADC easier, but our LO freq and RF must be ~1.5GHz. The mixer we want to buy does spec the IF as DC-1GHz, but I worry that there will be an issue having the IF so much smaller than the LO/RF. Any advice?
Thanks in advance.
