HMC-C200 question

Hi Hittite,

 

I asked about the frequency modulation bandwidth of HMC-C200 previously but did not get the right answer. The application engineer thought I was asking about the "tuning range" by Vtune port. I mean the frequency modulation bandwidth of the Vtune port. The data sheet says it has 100kHz bandwidth.  it also says: "For higher modulation bandwidths, contact the factory."

 

What the maximum modulation bandwidth you can make? I need as high FM modulation bandwidth as possible. It looks like there is a low pass filter for the Vtune port from the data sheet. Can you remove the low pass filter? I know typically other types of DRO Vtune have FM mod bandwidth of 10- 20 MHz, or so.
