Regarding the ADF4350:
1.) Why does the value of Frac and Mod seem to be related by integer number? I noticed in the eval board software, each time the program would set frac and mod values related by an integer value.
2.) I'd like to use ADF4350 in frequency range of 200 MHz to 2 GHz, with some gain to get LO power of 17dBm over this entire range. Can you recommend best combination of parts to achieve this?
