VCO HMC508: RF/4 Output

Dear All,


I wonder, if the RF/4 Output of the VCO HMC508  is useable ? While no described in data sheet per se, looking at the evaluation board, a DC- coupled RF/4 output seems to available. What is the output power at this (Pin 4 ?)  port ? How is the phase noise ?


If possible , I would like to use this RF/4 to feed a HMC698 PLL (I need both an RF signal of 7,36 GHz from the VCO, and 7,36/4=1,84GHz), to avoid an additional :2 divider.


Is this feasible ?
