What is the broadband noise floor of 10-20G VCO, HMC733LC4B at LSB &USB offsets of 3 to 6G ? Eg, VCO set at 15G, what is the noise floor from 9 to12G and 18 to 21G?
My goal is at least 160dBc below the carrier. If the output level is 5dBm, the noise floor must be below -155dBm/Hz or -160dBc/Hz.
I assume besides the VCO core, there is a buffer amp, so the noise floor will be much higher than -174dBm/Hz thermal limit.
