Hello, I am new to this forum and working on my first VHF transceiver design.
I have been evaluating the ADF4153A with the simulation software and have a bug. After setting everything up and running a simulation, I go back and increase my upper frequency…

You can test the various CP currents without changing the loop filter components. It will change the bandwidth and phase margin of the loop filter but it will give you an indication of if the CP current has an effect.
When you find a 'good' CP current…
The prescaler is needed to divide down the RF input to a frequency that the rest of the N divider can handle. The prescaler either divides by 8 or 9 depending on what is needed. This is all taken care of internally.

You need a PLL which drives a frequency doubler which drives an amplifier. Possible choices might be ADF4371 (PLL), HMC1105 (frequency doubler) and HMC7229 (amplifier). These are not the only choices.
This part is EAR99. The attached RFIC selection guide lists the ECCN codes for all of ADI's RF products.
