Other Parts Discussed in Thread: LMX2820
Tool/software:
Hello,
Am I correct in assuming that the floor noise of the LMX2594 (or LMX2820) is at thermal noise level (≈ -174 dBm/Hz)?
Floor noise is where you are far enough away from the carrier.
For example, 20 MHz and 100 MHz offsets.(Where not affected by VCO noise or loop filters.)
Does the use of a divider in the LMX2594 (or LMX2820) change the noise floor?
We want to calculate the noise when the start is an oscillator, just as we calculate the NF of a receiver circuit.
