Hi,
I want to perform a linear FMCW sweep from 13.4 to 14.0 GHz using a 100 MHz reference (I can change the XO frequency if you have another recommendation).
When performing such a wide sweep across 5 integer boundaries can I expect LMX2492 to maintain a "clean sweep" without any RF phase or amplitude discontinuities near the boundaries? This is critical for proper FMCW operation.
Related to this, I also read somewhere on this forum that the fractional counter can only "roll over 8 times". I guess that means one can only sweep across 8 integer boundaries? Are there other such limitations/considerations I should know about?
Thanks!
Christer
